Portfolio overview

TDA Research, Inc. has been granted 40 US utility patents between 2015 and 2025, placing TDA Research, Inc. at rank #8,120 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, TDA Research, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, TDA sits between Somos, Inc. (40 patents, rank #8,116) and TOYO Gosei Co., Ltd. (40 patents, rank #8,124) - the closest US assignees by grant volume. The composite Innovation Score of 51.2/100 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 19 grants, compared with 21 in the 2015–2019 window, a -10% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. TDA Research, Inc.'s 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TDA Research, Inc. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
