Portfolio overview

Photo Diagnostic Systems, Inc. has been granted 5 US utility patents between 2019 and 2022, placing Photo Diagnostic Systems, Inc. at rank #49,726 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in G01V (GEOPHYSICS; GRAVITATIONAL MEASUREMENTS; DETECTING MASSES OR OBJECTS; TAGS). As a US Corporation, Photo Diagnostic Systems, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Photo sits between Phoenix Conveyor Belt Systems Gmbh (5 patents, rank #49,722) and Picard Healthcare Technology (dongguan) Co. Ltd. (5 patents, rank #49,730) - the closest US assignees by grant volume. The composite Innovation Score of 25.5/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 4 grants, compared with 1 in the 2015–2019 window, a +300% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Photo Diagnostic Systems, Inc.'s 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Photo Diagnostic Systems, Inc. against peers pursuing similar technology classes.
