Portfolio overview

Sika Hamatite Co., Ltd. has been granted 9 US utility patents between 2022 and 2023, placing Sika Hamatite Co., Ltd. at rank #30,186 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in C09J (ADHESIVES; NON-MECHANICAL ASPECTS OF ADHESIVE PROCESSES IN GENERAL; ADHESIVE PROCESSES NOT PROVIDED FOR ELSEWHERE; USE OF MATERIALS AS ADHESIVES). As a Foreign Corporation, Sika Hamatite Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sika sits between Shuttle Pharmaceuticals, Inc. (9 patents, rank #30,182) and Simo Holdings Inc. (9 patents, rank #30,190) - the closest US assignees by grant volume. The composite Innovation Score of 48.6/100 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. Historical data spans 2022 through 2023, with 9 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. Sika Hamatite Co., Ltd.'s 14.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sika Hamatite Co., Ltd. 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.
