Cognitive Testing Patents

Curated summaries of patents covering computerised cognitive assessment systems — the IP landscape behind the devices and methods in cantab, nonverbal-cognitive-tasks, and preclinical-drug-screening. Each entry specifies two dimensions of particular interest:

  1. Target species: Does the patent apply to humans, animals, or both?
  2. Brain recording: Does the system use EEG/ERP/neural recording, or is it purely behavioural (touchscreen/accelerometer/camera)?

One entry per patent (or patent family), each with assignee, inventors, key dates, and a summarising paragraph. Verified against Google Patents records. See visual-prosthesis-patents for the companion patent page in the visual-prosthesis domain.

Patents

US20230320647A1 — Cognitive health assessment for core cognitive functions (McMaster University, 2023)

Assignee: McMaster University · Inventors: John Francis Connolly, Kyle Ingram Ruiter, Rober Boshra · Filed: 2019-07-16 (US16/513,469; PCT/CA2019/050982) · Published: 2023-10-12 · Status: Active (US); WO ceased; continuation US19/248,349 pending (filed 2025-06-24)

DimensionValue
Target speciesHuman — 306 “patient” mentions; 13 “human”; zero animal/rodent/primate mentions
Brain recordingYES — EEG + ERP — 64 EEG mentions; 49 ERP; 40 P300; 45 MMN; electrodes on head

An EEG-based cognitive assessment system from the McMaster/Connolly group. The system presents intermixed/repeated sensory stimuli (auditory tones, vibrations, olfactory, or visual) while recording EEG, extracts ERP signal components (P300, MMN, CVMT), and classifies cognitive health using machine learning (G06N20/00). The design probes both pre-attentive brain responses (mismatch negativity — MMN) and consciously controlled attention (P300), enabling assessment of attention/concentration, information processing, and working memory in patients who may not be able to give active behavioural responses. Claim 20 specifies: sensor apparatus with EEG electrodes, sensory output devices, stimulus presentation mechanism, waveform feature extractor for ERP, and a processor comparing ERP data to a neurophysiological assessment output. The Connolly group is known for passive-attention MMN paradigms that probe pre-attentive sensory processing — this patent extends that work into a structured cognitive-health assessment product. Classified under A61B5/369 (EEG), A61B5/377 (EEG evoked responses), A61B5/165 (depression/anxiety evaluation), and A61B5/168 (attention deficit/hyperactivity). 1

US11154227B2 — Portable neurocognitive assessment and evaluation system (Hhitt Inc, 2021)

Assignee: Hhitt Inc · Inventor: Jacob Benford · Priority: 2011-03-18 (provisional 61/454,287) · Filed: 2012-03-16 (US13/422,125, abandoned); continuation 2019-03-22 (US16/362,049) · Granted: 2021-10-26 · Status: Active · Adjusted expiration: 2032-12-03

DimensionValue
Target speciesHuman — 9 “human” mentions; 35 “user”; 25 “subject”; zero animal/rodent/primate mentions
Brain recordingNO — purely behavioural: touchscreen, accelerometer (balance), camera (eye tracking); no EEG/electrodes/ERP

A portable, tablet-based (iPad/Galaxy Tab) neurocognitive assessment system for acute concussion / mild traumatic brain injury (MTBI) field diagnosis. The system runs a 12-test battery via downloadable software: balance (accelerometer — keep a circle within a circle while standing on one leg), reaction time (tap moving dots), coordination (trace S-curve with finger), recollection, sequence memory, pattern recognition, color recognition (Stroop), impulse control, problem solving, eye movement tracking (camera + grid overlay), and short/long-term memory. The device features dual displays (touchscreen + second display), Internet connectivity for uploading results to a server, PIN-based subject registration, and normative/historical comparison. Notably no brain recording — the system is entirely behavioural, using the tablet’s built-in sensors (touchscreen, accelerometer, camera) as measurement modalities. Classified under A61B5/16 (psychotechnics), A61B5/162 (reaction time), A61B5/163 (eye movement/gaze/pupil), A61B5/165 (depression/anxiety), and G09B5/02 (educational appliances). The comprehensive test battery is conceptually a portable CANTAB-like system aimed at sports medicine / field-deployable concussion screening. 2

US11857349B2 — Apparatus and related method to facilitate test via a computing device (Cleveland Clinic / Biogen, 2024)

Assignee: Cleveland Clinic Foundation; assigned to Biogen MA Inc. (2020-02-21) · Inventors: Jay L. Alberts, David D. Schindler, Jane Rhodes · Filed: 2016-04-18 (US16/578,892) · Granted: 2024-01-02 · Status: Active

DimensionValue
Target speciesHuman — 24 “human” mentions; 90 “user”; 141 “patient”; 1 “animal” (passing reference); zero rodent/monkey/primate
Brain recordingNO — physical apparatus (pegboard overlay on touchscreen); capacitive coupling; accelerometer (14 mentions); no EEG/electrodes/ERP

A physical apparatus that converts a standard tablet touchscreen into a cognitive/motor testing device. A hinged test fixture with a 2D array of receptacles overlays the tablet display; contact members (pegs) inserted into receptacles are detected by the tablet’s capacitive touchscreen — even without user finger contact on the pegs. The hinge forms part of an electrical path to the device’s ground, ensuring reliable capacitive detection. The system stores test module instructions for “at least one of a neurological or cognitive function test” and records results in response to user interaction (claim 10). The Biogen/Cleveland Clinic partnership (Alberts lab is known for MS motor-cognitive research) suggests the primary use case is multiple sclerosis motor-cognitive assessment — pegboard tasks (9-hole peg test, Grooved Pegboard) are standard MS outcome measures. This is conceptually an extension of the CANTAB touchscreen paradigm with a physical manipulandum layer, but no brain recording — the modalities are touch interaction, capacitive peg detection, and accelerometer-based movement tracking. Classified under A61B5/103 (body shape/pattern/movement), A61B5/11 (head/hand tremor/mobility), and A61B3/028 (visual acuity testing). 3

US20170039303A1 (granted US10387587B2) — Computer simulation of animal training scenarios and environments (Radio Systems Corp, 2017)

DimensionValue
Target speciesAnimal (dog) — 107 “animal”; 229 “dog”; 6 “human” (the human is the trainer, not the subject); zero rodent/monkey/primate
Brain recordingNo — simulation software with peripheral input devices; no EEG/electrodes/ERP

A virtual environment for simulating pet training scenarios — the user practices using electronic training collars (shock/vibration/sound) on a simulated dog in a simulated environment before using the physical product. The animal’s behaviours (sit, heel, avoid jumping on furniture, stop barking) and the training product’s stimulus delivery (positive/negative) are simulated and evaluated. Classified under A01K15/02 (animal training equipment, mazes/labyrinths) and A01K15/021 (electronic training for dogs/cats), not medical diagnostics. Tangentially related to cognitive testing — it simulates behavioural conditioning, but for pet owner training rather than cognitive assessment. 4

CN114096194B — Systems and methods for cognitive training and monitoring (Aceral Co Ltd, 2022)

Assignee: Aceral Co Ltd · Inventors: Yair Gilutz, Shai Granot, Anna Izotzky · Filed: 2020-05-04 (CN202080040282.1A; US17/615,200) · Granted: CN114096194B, 2022 · Status: Active · Anticipated expiration: 2040-05-04

DimensionValue
Target speciesHuman — 9 “human”; 212 “user”; 2 “patient”; zero animal/rodent/primate
Brain recordingOptional — EEG + eye tracking — 23 EEG mentions; EEG sensor in claim 18; eye-tracking imager in claim 22; ML (LSTM/RNN) for success prediction

A cognitive training and monitoring system from Aceral (Israeli company). The core method is behavioural: users respond to cognitive training exercises, and a machine-learning pipeline (recurrent neural networks with LSTM, trained via supervised, unsupervised, and reinforcement learning) predicts training success rate, modifies the training program accordingly, and issues alarms if performance degrades. EEG (claim 18) and eye tracking (claim 22) are optional sensors for user profiling and attention monitoring — not the primary modality. Classified under A61B5/16 (psychotechnics), A61B5/4088 (cognitive diseases — Alzheimer/dementia), G16H20/70 (mental therapies), and G06N3/0442 (LSTM). The system targets cognitive diseases including Alzheimer’s and dementia, making it a therapeutic training tool rather than pure assessment. 5

US11676506B1 — Cognitive training method (Sylvain Moreno, 2023)

Assignee: Individual (Sylvain Jean-Pierre Daniel Moreno) · Inventor: Sylvain Jean-Pierre Daniel Moreno · Priority: 2011-04-20 (US13/090,677) · Filed: 2013-09-04 (US14/017,493, expired-fee); continuation 2022-06-30 (US17/810,227) · Granted: 2023-06-13 · Status: Active · Anticipated expiration: 2031-04-20

DimensionValue
Target speciesHuman (children) — 13 “human”; 795 “user”; 142 “animal” (ALL refer to animated cartoon animal characters used as visual stimuli, NOT animal testing); 3 “monkey” (stimulus characters); zero rodent
Brain recordingOptional — EEG/ERP — portable EEG (1-10 leads) as optional measurement; ERP data (P2, Go/No-Go) shown as evaluation outcome; 2 EEG mentions; 9 ERP mentions

A cognitive training method from Sylvain Moreno (Baycrest/NOSM University, known for auditory cognitive training in children). The primary method is behavioural: cue-probe-distractor tasks with adaptive difficulty (perceptual + conceptual), using animated animal characters paired with musical sounds as cross-modal stimuli. Input devices include touchscreen, motion sensor, accelerometer, microphone. The patent includes ERP evidence (FIG. 33-34): grand-average ERP at Cz for Go/No-Go, with P2 amplitude increasing significantly post-training (7.3 µV → 11.6 µV, p<0.05), interpreted as training-related improvement in conflict/decision processing. EEG is an optional evaluation tool, not the primary modality. The Go/No-Go paradigm and adaptive difficulty are directly relevant to the CANTAB/touchscreen cognitive testing framework. 6

US20230097582A1 — System and method for selecting and executing training protocols for autonomously training an animal (Companion Labs, 2023)

Assignee: Companion Labs Inc · Inventors: Paul Mundell, John Honchariw, Noémie A. Guérin, Sayli Benadikar, Tim Genske · Filed: 2021-01-11 (US17/146,411) · Published: 2023-03-30 · Status: Active (US17/146,411); US18/074,205 abandoned

DimensionValue
Target speciesAnimal (dog) — 79 “animal”; 641 “dog”; 8 “human” (the human is the trainer, not the subject); zero rodent/monkey/primate
Brain recordingNo — video feed + treat dispenser + optical sensor (computer vision); no EEG/electrodes/ERP

An autonomous animal training system from Companion Labs (San Francisco pet-tech startup). A training apparatus with an integrated optical sensor (camera) and treat dispenser runs autonomous training protocols: it detects the dog in the video feed, dispenses treats based on performed behaviours, calculates a training score, tracks anxiety level from video behaviour analysis, and generates prompts for manual (human-guided) training when the autonomous score falls below threshold. Classified under A01K15/02 (animal training equipment), A01K15/0201 (treat dispensers), and G06V40/20 (behaviour/gesture recognition). No brain recording. Tangentially related to cognitive testing — it is automated operant conditioning with computer-vision-based behaviour analysis, structurally similar to preclinical touchscreen chambers but designed for pet training. 7

US20220207902A1 — Automatically discovering, characterizing, classifying and labeling animal behavior (Harvard University, 2022)

Assignee: Harvard University · Inventors: Sandeep Robert Datta, Alexander B. Wiltschko · Filed: 2013-05-10 (EP13788526.5A; US17/581,326, 2022-03-23) · Published: 2022-06-30 · Status: Withdrawn · Family: EP4198926A1 (EP, withdrawn); WO2013170129A1 (WO)

DimensionValue
Target speciesAnimal (mouse/rodent) — 230 “animal”; 109 “mouse”; 9 “rodent”; 3 “primate”; 23 “subject”; zero human-as-subject
Brain recordingNo — depth camera (95 mentions) + touch-sensitive device (33) + video (64); no EEG/electrodes/ERP

The Datta Lab (Harvard) automated animal behaviour phenotyping system. Uses 3D depth cameras and machine-learning (Kalman filter contour tracking → PCA/SVD/ICA dimensionality reduction → clustering) to automatically discover, classify, and label mouse behaviours without human annotation. Produces “quantitative behavioural primitives” — unsupervised behavioural categories from multi-dimensional pose/posture data. Classified under G06V40/10 (animal body recognition), A01K29/005 (monitoring animal activity), A01K67/00 (breeding animals), and A61B5/11 (body movement measurement). Withdrawn, but the underlying work became the commercial DeepLabCut ecosystem and the Wiltschko/Datta behavioural phenotyping platform. Directly relevant to preclinical cognitive testing because it provides the automated behavioural measurement infrastructure that operant/touchscreen experiments rely on for phenotyping. 8

AU2022409850A1 — Computer-based systems for acquiring and analyzing observational subject data (PGI Drug Discovery, 2023)

Assignee: PGI Drug Discovery LLC · Inventors: Hasan Almawi, Alberto Ambesi-Impiombato, Mukesh Bansal, Daniela Brunner, et al. · Filed: 2022-12-16 (PCT/US2022/053289) · Status: Ceased (AU)

DimensionValue
Target speciesAnimal (rodent) — 348 “animal”; 111 “rodent”; 54 “mouse”; 13 “rat”; 469 “subject”; 24 “human” (translational context)
Brain recordingYES — pharmacological EEG (pEEG) — 152 EEG mentions; 23 “electrode”; 50 “neural”; pEEG is a core modality, not optional

A comprehensive rodent drug-screening platform from PGI Drug Discovery (PsychoGenics/Innovive partnership). An instrumented enclosure with sensing devices (cameras, EEG electrodes) captures observational data from a rodent administered a drug. A machine-learning pipeline extracts instant behavioural features (forward walk, immobile, turn around, backward walk) → higher-order features (state features, motif features, domain features) via supervised/unsupervised ML → predicts drug class labels. The pEEG (pharmacological EEG) dimension is core — rodent pEEG signatures translate to receptor affinity predictions (e.g., benzodiazepine receptor). This is the first patent in this collection with both rodent subjects AND brain recording as a primary modality. Classified under G16H70/40 (drug side effects), A61B5/4848 (treatment effects monitoring), and G06V10/40 (image feature extraction). Ceased in AU, but the PCT family may be active in other jurisdictions. 9

US20180007862A1 — Systems, methods and apparatus for rodent behavioural monitoring (University of Toronto, 2018)

Assignee: University of Toronto · Inventors: Robert P. Bonin, David Dubins, Jeffrey Mogil, Irene Lecker · Filed: 2017-07-05 · Status: Abandoned

DimensionValue
Target speciesAnimal (rodent) — 198 “rodent”; 18 “animal”; 12 “mouse”; zero primate/monkey
Brain recordingNo — cage-lid interaction sensor (various modalities: capacitive, inductive, load cell, optical); 123 “sensor”; no EEG/ERP

A home-cage rodent behavioural monitoring system from University of Toronto (Bonin/Dubins/Mogil). Non-invasive sensors detect interactions with the cage lid (climbing, hanging) as a health/behaviour proxy. Can be retrofitted to existing rodent cages or supplied as a replacement sensorized lid. Supports multiple individually-identified rodents (RFID or time-stamped location). Classified under A01K1/031 (cages for laboratory animals) and A01K29/005 (monitoring/measuring activity). Abandoned. Relevant to the automated cognitive testing landscape because it represents the home-cage monitoring approach (passive, longitudinal, non-invasive) that complements active operant/touchscreen testing — cage-lid climbing is used in pain and welfare assessment. 10

CN205357588U — Water supply device for non-human primate cognitive function touch screen test cage (Kunming Institute of Zoology, CAS, 2016)

Assignee: Kunming Institute of Zoology, CAS · Inventors: Wu Shihao, Yang Shangchuan, Hu Yingzhou, Zhang Lin Heng · Filed: 2016-01-24 (CN201620065028.8U) · Status: Expired — Fee Related

DimensionValue
Target speciesAnimal (non-human primate) — 9 “animal”; 6 “primate”; 5 “monkey”; zero rodent/mouse
Brain recordingNo — mechanical water reward delivery device; infrared sensor on nozzle; no EEG/electrodes

A physical apparatus component for NHP touchscreen cognitive testing from the Kunming Institute of Zoology (CAS) — a major Chinese primate research centre. An adjustable water reward nozzle (vertical + horizontal adjustment via screw + rack-and-pinion mechanism) positioned in front of the touchscreen in a primate cognitive test cage. The miniature infrared sensor on the nozzle detects when the animal drinks. Though narrow in scope (just the water reward mechanism) and expired, it is notable as a rare patent specifically targeting non-human primate touchscreen cognitive testing — the NHP equivalent of the Bussey-Saksida rodent touchscreen chamber. NHP touchscreen cognitive testing is the direct translational bridge between rodent touchscreen tasks and human CANTAB. 11

CN112022091A — Animal behavioristics test system (Shenzhen Institute of Advanced Technology, CAS, 2020)

Assignee: Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences (SIAT) · Inventors: Liu Haoran, Wang Feng, Wang Liping (pinyin transliteration of the CN record) · Filed: 2019-06-04 (CN201910483279.6A; PCT/CN2019/120889, ceased) · Published: 2020-12-04 · Status: Pending (CN)

DimensionValue
Target speciesAnimal (rodent/mouse) — 129 “animal” and 75 “experimental animal” mentions; background concerns anaesthetised mice; “rodents such as mice” whose dark-environment activity matches their natural behaviour
Brain recordingNo — visible-light + infrared video monitoring; an optical pulse (optogenetic) stimulation module is an intervention, not recording; no EEG/electrodes

An animal behaviour testing system for innate-fear and arousal-state research from SIAT (CAS), designed to fix four shortcomings of existing rigs: poor airtightness around anaesthetic gas, light-only video, manual stimulus triggering, and narrow function. The box has a gas inlet plus gas recovery and sampling tubes (recovery > inlet > sampling diameters, claim 6) — containment for anaesthetised preparations with researcher safety in mind. Stimuli are presented via a top-wall screen (claim 3; light, sound and odour devices, claim 10). The video monitoring module pairs a visible-light component for lit conditions with an infrared component (IR-filter auxiliary box) for behaviour monitoring in the dark — the natural phase for nocturnal rodents (claims 2, 4). The optical pulse stimulation module (laser generator + waveform generator, fibre suspended on a universal-joint rod to the animal’s head; claims 7-8) enables bidirectional optogenetic modulation of specific brain regions, with behaviour read out on video — aimed at dissecting the neural circuits of innate fear and arousal, with stated translational relevance to fear-related disorders such as PTSD and anxiety. A glove port allows animal adjustment without opening the box (claim 9). Classified under A61B5/16 (psychotechnics), A61B5/40 (nervous-system evaluation), A61B5/48, and A61D7/00-A61D7/04 (animal anaesthesia delivery). 12

CN114532247A — Cognitive ability test system (Shenzhen Institute of Advanced Technology, CAS, 2022)

Assignee: Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences (SIAT) · Inventors: Ji Wenjing, Yang Xing, Ren Zhen, Lu Zhonghua, Zhu Yuyuan, Xu Dongdong, Li Mengqi (pinyin transliteration of the CN record) · Filed: 2020-11-20 (CN202011313055.XA) · Published: 2022-05-27 · Status: Pending (CN)

DimensionValue
Target speciesAnimal (non-human primate) — 12 “monkey”; 6 “primate” (mostly “non-human primate”); 14 “animal”; the worked embodiment is a monkey performing a touchscreen task; zero rodent
Brain recordingNo — touchscreen tasks + liquid reward + video capture for remote monitoring; no EEG/electrodes

An in-cage (home-cage) cognitive ability testing system for non-human primates from SIAT (CAS). The device combines a task detection unit and a linking structure placed on top of its detection face: the structure suspends the whole unit on the animal’s daily living cage (height matched to the cage opening by a retractable hook, claim 2). The motivation: routine NHP cognitive testing requires transferring animals to a test cage — a source of environmental change, handling, experimenter time, and one-at-a-time throughput; the in-cage design reduces environment change (claimed to improve result accuracy), eliminates transfer, and allows many animals to be tested simultaneously. Hardware: operation terminal + touchscreen display for task presentation and response capture; a liquid supply reward system (single-chip microcomputer driving a micro-pump, storage bottle, conduit, outlet fixed on the same side as the screen; claims 5-7); a transparent screen-protection baffle with an access opening (claims 8-9); and a video capture device feeding a remote workstation so the experimenter can monitor several rigs remotely (claim 10). The background frames the use case as cognitive testing of non-human primate autism models. Classified under A01K29/005 (monitoring or measuring animal activity). 13

CN118592356A — Animal cognitive training system, animal cognitive training method and virtual device (Institute of Biophysics, CAS, 2024)

Assignee: Institute of Biophysics, Chinese Academy of Sciences (IBP) · Inventors: Jiang Liuming, Liu Ning, Liang Zhen (pinyin transliteration of the CN record) · Filed: 2024-08-08 (CN202411081256.XA) · Published: 2024-09-06 · Status: Pending (CN)

DimensionValue
Target speciesAnimal (non-human primate) — 207 “animal”; 8 “monkey”; 4 “NHP”; background and worked examples address NHPs; zero rodent/mouse
Brain recordingNo — touchscreen touch-position capture + remote display/control link; no camera/video, no EEG/electrodes

A remote-operated animal cognitive training system from the Institute of Biophysics, CAS. Two-tier architecture: an upper control machine, placed away from the animal feeding room, issues training instructions and synchronously displays the running experiment and the animal’s touch positions in real time so a user can supervise and send control instructions from afar (claim 7); a lower execution machine near the animals starts the experiment on instruction, presents it via a display-touch module, captures the animal’s touch-position information, matches it against preset training actions, and triggers rewards — water via a solenoid valve on a water outlet pipe (claim 2), or fruit via an electric bin gate on a fruit bin (claim 3). Claims cover the system (claims 1-7), a corresponding training method (claim 8) and a virtual/software device embodiment (claim 9). The stated motivation: awake NHP experiments require lengthy behavioural training, and standard laboratory-environment testing “deviates from the NHP population” and poorly reflects autonomous behaviour in natural environments — testing at/near the animal room under remote supervision is claimed to make behaviour more natural and neural-mechanism research more accurate. Classified under A01K15/02 and A01K15/00 (animal training/exercising equipment). Complements the SIAT in-cage NHP system (CN114532247A). 14

CN109566447A — Touch-screen research system for non-human primate movement and cognitive function (Institute of Pharmacology and Toxicology, AMMS, 2019)

DimensionValue
Target speciesAnimal (non-human primate) — 44 “animal”; 42 “primate” (mostly “non-human primate”); 3 “monkey”; 3 “macaque”; worked embodiment fixes a macaque in the chair; zero rodent
Brain recordingSynchronised (external) — no EEG of its own — built-in wireless EMG of upper-limb muscles + eye tracker + four-camera hand tracking; brain neural activity acquired “in conjunction with brain electricity or neural signal collecting system”; claim 8 notes synchrony with cranial-nerve-information recording

A multi-modal NHP movement-and-cognition research rig from the Institute of Pharmacology and Toxicology of AMMS, built around a restraint chair (steel frame, transparent acrylic basket, neck-ring fixation; arms free to reach the touchscreen). It unifies streams that NHP labs usually record with separate setups: touchscreen task presentation (visual/auditory stimuli) and touch capture; water-supply reward (nozzle, dual conduits, solenoid valve, drive control circuit); eye tracking (infrared camera + lamp; bilateral eye movement and blinks); four-camera hand-trajectory tracking (fluorescent dye markers, adjustable brackets, video capture card); and wireless myoelectrical recording of upper-limb muscles (electrode sensor → receiver → signal acquisition; claim 8). A slave computer integrates the modules; a host computer sets training/associative-mode parameters (reward time, audiovisual feedback timing) online and stores results; LED warning light, prepare button and buzzer complete the rig. The background cites the tablet 5-CSRTT Alzheimer’s study, the monkey CANTAB touch-screen system and a Stanford macaque motor-function touch-screen system as prior art, and motivates the design by the inability of existing devices to study limb movement, eye movement and brain signals together in accurate, repeatable multi-task experiments. Classified under A01K15/00, A01K15/02, A01K15/027. 15

CN219421883U — Behavioural testing device matched to non-human primate rearing cages (Hainan University, 2023)

Assignee: Hainan University · Inventors: Yue Feng, Yang Yong (pinyin transliteration of the CN record) · Filed: 2022-12-23 (CN202223458936.8U) · Granted: 2023-07-28 · Status: Expired — fee related · Anticipated expiration: 2032-12-23

DimensionValue
Target speciesAnimal (non-human primate) — 109 “animal”; 43 “primate”; 10 “monkey”; worked example tests 8 naive cynomolgus macaques on DMTP; zero rodent
Brain recordingNo — purely mechanical cage-docked test device (task panels, sliding doors, fine-motor rack); two video recorders document test reactions; no EEG/electrodes

A utility model from Hainan University that brings the behavioural test to the animal’s own cage: the device body (front/left/right side plates) docks against the rearing cage, its front-plate “animal activity window” forming the interaction opening; a test support plate between the side plates takes a flat plate for DMTS/DMTP cognitive-memory tests or a hole-perforated plate to mount fine-motor fixtures; interchangeable sliding-door panels — grid door, double-hole, left/right single-hole — in a door slot at the rear of the front plate let zero, one or both hands through for different task types (claim 3); an opaque pull plate occludes the animal between trials (claim 6); the upper front protrudes as a rearing-cage docking chamber (claim 7). The stated motivation is the instability that transfer to a test room produces (“panic and unstable emotion”), degrading cooperation and result objectivity; testing at the familiar cage is claimed to fix this. The description documents two video recorders (side panorama + close-up) and a worked example comparing the device against conventional testing in 8 naive cynomolgus macaques on DMTP (order counterbalanced 1-4/5-8, on-site indicator evaluation). Stated repertoire: upper-limb fine motor, cognitive memory, anxiety/depression, facial expression, addictive-drug testing. Third transfer-free home-cage design in this collection, after SIAT (CN114532247A) and IBP (CN118592356A). 16

Dimensions of comparison

Target species

All three patents target humans exclusively. None mention animal models, rodent testing, or non-human primate protocols. This is a significant distinction from the nonverbal-cognitive-tasks and preclinical-drug-screening concept pages, where the same cognitive tasks (DMS, ID/ED, attention) are explicitly translational — validated across humans, NHPs, and rodents via cantab and its preclinical analogues (e.g. MonkeyCANTAB, Bussey-Saksida touchscreen chambers). The patent landscape for cognitive testing is human-clinical-focused: concussion diagnosis (Hhitt), MS motor-cognitive (Cleveland Clinic/Biogen), and general cognitive health (McMaster). Preclinical animal cognitive testing apparatus — operant chambers, touchscreen rodent systems — does not appear to be heavily patented in the same way; it lives in the academic literature and commercial product space (Campden Instruments, Lafayette Instruments, Bussey-Saksida chambers).

With the second batch, two animal-target patents enter the landscape: US20170039303A1 (Radio Systems Corp — dog training simulation, A01K classification) and US20230097582A1 (Companion Labs — autonomous dog training with computer vision, A01K classification). Both target dogs, not laboratory animals. They are classified under animal husbandry (A01K), not medical diagnostics (A61B), and are tangentially related — they are behavioural conditioning systems, not cognitive assessment. However, they highlight a structural parallel: the Companion Labs autonomous training apparatus (video detection → treat dispenser → training score → protocol selection) is architecturally similar to a preclinical operant chamber (stimulus → response → reinforcement → adaptive protocol), except using computer vision instead of lever-press/touchscreen detection and targeting pet dogs rather than rodents.

A third batch introduces laboratory-animal-specific patents: US20220207902A1 (Harvard/Datta — mouse behaviour phenotyping via depth camera, withdrawn), AU2022409850A1 (PGI Drug Discovery — rodent drug screening with EEG + behavioural monitoring, ceased), US20180007862A1 (University of Toronto — rodent home-cage lid-interaction monitoring, abandoned), and CN205357588U (Kunming Institute of Zoology/CAS — NHP touchscreen test cage water reward, expired). These are the first patents in the collection explicitly targeting laboratory animals (mice, rats, non-human primates) for research rather than pet training. The PGI Drug Discovery patent is particularly significant — it is the first with both rodent subjects AND brain recording (pEEG) as a primary modality, bridging the two dimensions. The Kunming NHP touchscreen apparatus is a rare patent covering the NHP translational bridge between rodent touchscreen tasks and human CANTAB.

A fourth batch adds two more laboratory-animal patents, both from the Shenzhen Institute of Advanced Technology (SIAT), CAS — a second CAS institute in the collection, contributing instrumentation at two ends of the animal cognitive-behaviour space. CN112022091A is a behaviour box for innate-fear and arousal research that combines airtight anaesthetic-gas management, dual-mode video monitoring (visible light + infrared for behaviour in the dark), and an optogenetic stimulation module — a modern mouse systems-neuroscience rig rather than a cognitive assessment per se. CN114532247A applies the in-cage testing paradigm familiar from rodent automated home-cage systems to non-human primates: a touchscreen task device that suspends from the animal’s living-cage top, eliminating transfer to a test cage and enabling parallel testing — complementing the Kunming test-cage reward device (CN205357588U) to give the collection an NHP line from test-cage component to a full in-cage platform.

A further addition — CN118592356A from the Institute of Biophysics, CAS (IBP; a third CAS institute in the collection) — brings a two-tier remote-operation architecture to the NHP line: a lower execution machine stationed in the animal room runs touchscreen training (touch positions matched against preset actions; water or fruit rewards), while an upper control machine located away from the colony issues the instructions and relays a real-time view of the experiment and the animal’s touches for remote supervision and control. The stated aim again is testing animals in their living environment so behaviour better reflects autonomous, natural conditions.

A sixth batch adds two more Chinese non-human-primate systems, extending the NHP line to five patents and bracketing the restraint/naturalism axis. CN109566447A (Institute of Pharmacology and Toxicology of AMMS, Beijing) is the collection’s most instrumented NHP rig — a seated-restraint chair unifying a touchscreen task with eye tracking, four-camera hand tracking and wireless upper-limb EMG, synchronisable with external neural recording; its background cites the monkey CANTAB touch-screen system and a Stanford macaque motor-function system as the prior art it improves on. CN219421883U (Hainan University) is the third transfer-free home-cage design (after SIAT CN114532247A and IBP CN118592356A) — this time a purely mechanical device that docks to the animal’s rearing cage, justified by reduced transfer stress and supported by a counterbalanced DMTP comparison in 8 naive cynomolgus macaques: maximum instrument control under restraint (AMMS) at one end, minimal disturbance in the home environment (Hainan) at the other.

Only the McMaster patent uses brain recording (EEG/ERP) as the primary modality. Two additional patents (Aceral, Moreno) include EEG as an optional sensor — in both cases, the primary method is behavioural (cognitive training exercises with adaptive difficulty), and EEG serves as a supplementary evaluation or profiling tool. The remaining four are purely behavioural — relying on touchscreen interaction, physical manipulanda, accelerometers, cameras, or computer vision. This bifurcation mirrors the broader cognitive-assessment field: EEG/ERP-based passive assessment (no active behavioural response needed; can be used with non-communicative patients) vs. behavioural active assessment (touchscreen reaction time, peg placement, balance, eye tracking — requires patient engagement and motor function). The McMaster MMN/P300 approach is particularly relevant to the nonverbal-cognitive-tasks framework because it probes pre-attentive sensory processing — the same information-processing stage that the affective bias and judgement bias tasks target behaviourally. The Moreno and Aceral patents extend this by adding EEG as an outcome measure for cognitive training — demonstrating brain-level changes (P2 amplitude) that complement behavioural performance scores. The PGI Drug Discovery patent (AU2022409850A1) is unique: it uses pharmacological EEG (pEEG) as a primary modality in a rodent drug-screening context — not for cognitive assessment per se, but for predicting drug class from brain-signal signatures. This makes it the only patent in the collection where brain recording is both primary and applied to animal subjects. The fourth batch keeps the same split: neither SIAT patent records neural activity — one adds optogenetic stimulation without recording (CN112022091A), and the other carries the transfer-free, in-cage design principle into NHP cognitive testing (CN114532247A), a paradigm previously seen in this collection only in rodent home-cage systems. CN118592356A (IBP) continues the pattern: purely behavioural instrumentation — touchscreen, reward delivery, and a remote-control link — with the control station itself decoupled from the animal room. The sixth batch keeps the same split — the AMMS rig records body signals (eye, hand, EMG) and is only synchronisable with external neural recording, while the Hainan University device is purely mechanical (video documentation only).
