Portfolio overview

Showa Corporation has been granted 207 US utility patents between 2015 and 2022, placing Showa Corporation at rank #1,942 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in F16F (SPRINGS; SHOCK-ABSORBERS; MEANS FOR DAMPING VIBRATION). As a Foreign Corporation, Showa Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Showa sits between Ideal Industries Lighting Llc (207 patents, rank #1,938) and Transform SR Brands Llc (207 patents, rank #1,946) - the closest US assignees by grant volume. The composite Innovation Score of 49.3/100 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 32 grants, compared with 175 in the 2015–2019 window, a -82% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Showa Corporation's 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Showa Corporation against peers pursuing similar technology classes.

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.
