Portfolio overview

Wuhan Tianma Microelectronics Co., Ltd. Shanghai Branch has been granted 183 US utility patents between 2022 and 2025, placing Wuhan Tianma Microelectronics Co., Ltd. Shanghai Branch at rank #2,161 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in G09G (ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION). As a Foreign Corporation, Wuhan Tianma Microelectronics Co., Ltd. Shanghai Branch is one of the more focused assignees in the PatentsView dataset. By volume, Wuhan sits between Montres Breguet S.a. (183 patents, rank #2,157) and Koenig & Bauer Ag (182 patents, rank #2,165) - the closest US assignees by grant volume. The composite Innovation Score of 66.2/100 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. Historical data spans 2022 through 2025, with 183 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Wuhan Tianma Microelectronics Co., Ltd. Shanghai Branch's 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wuhan Tianma Microelectronics Co., Ltd. Shanghai Branch 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.
