Portfolio overview

LTC Co., Ltd. has been granted 10 US utility patents between 2015 and 2025, placing LTC Co., Ltd. at rank #26,736 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in G03F (PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; MATERIALS THEREFOR; ORIGINALS THEREFOR; APPARATUS SPECIALLY ADAPTED THEREFOR;). As a Foreign Corporation, LTC Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, LTC sits between Loomia Technologies, Inc. (10 patents, rank #26,732) and Lumiphore, Inc. (10 patents, rank #26,740) - the closest US assignees by grant volume. The composite Innovation Score of 29.0/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. LTC Co., Ltd.'s 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LTC Co., Ltd. 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.
