Portfolio overview

Enplas Corporation has been granted 367 US utility patents between 2015 and 2025, placing Enplas Corporation at rank #1,157 across all assignees tracked by PlainPatent. This portfolio spans 74 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.1 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Enplas Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Enplas sits between St. Jude Medical, Atrial Fibrillation Division, Inc. (368 patents, rank #1,153) and Westinghouse Electric Company Llc (367 patents, rank #1,161) - the closest US assignees by grant volume. The composite Innovation Score of 55.1/100 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 178 grants, compared with 189 in the 2015–2019 window, a -6% 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. Enplas Corporation's 8.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 74 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Enplas 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.
