Portfolio overview

Appotronics Corporation Limited has been granted 192 US utility patents between 2015 and 2025, placing Appotronics Corporation Limited at rank #2,061 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in G03B (APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR). As a Foreign Corporation, Appotronics Corporation Limited is one of the more focused assignees in the PatentsView dataset. By volume, Appotronics sits between Solventum Intellectual Properties Company (193 patents, rank #2,057) and Opple Lighting Co., Ltd. (192 patents, rank #2,065) - the closest US assignees by grant volume. The composite Innovation Score of 60.6/100 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 134 grants, compared with 58 in the 2015–2019 window, a +131% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Appotronics Corporation Limited's 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Appotronics Corporation Limited against peers pursuing similar technology classes.
