Portfolio overview

SMK Corporation has been granted 201 US utility patents between 2015 and 2025, placing SMK Corporation at rank #1,994 across all assignees tracked by PlainPatent. This portfolio spans 62 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.7 claims per patent with primary concentration in H01R (ELECTRICALLY-CONDUCTIVE CONNECTIONS; STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS). As a Foreign Corporation, SMK Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, SMK sits between Enseo, Llc (201 patents, rank #1,990) and Commscope, Inc. Of North Carolina (200 patents, rank #1,998) - the closest US assignees by grant volume. The composite Innovation Score of 50.7/100 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 77 grants, compared with 124 in the 2015–2019 window, a -38% 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. SMK Corporation's 4.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 62 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SMK 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.
