Portfolio overview

Epcos Ag has been granted 295 US utility patents between 2015 and 2022, placing Epcos Ag at rank #1,419 across all assignees tracked by PlainPatent. This portfolio spans 70 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.1 claims per patent with primary concentration in H10N (ELECTRIC SOLID-STATE DEVICES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Epcos Ag is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Epcos sits between Huizhou TCL Mobile Communication Co., Ltd. (297 patents, rank #1,415) and Macom Technology Solutions Holdings, Inc. (295 patents, rank #1,423) - the closest US assignees by grant volume. The composite Innovation Score of 54.6/100 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 50 grants, compared with 245 in the 2015–2019 window, a -80% 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. Epcos Ag's 15.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 70 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Epcos Ag 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.
