Portfolio overview

Niterra Co., Ltd. has been granted 60 US utility patents between 2023 and 2025, placing Niterra Co., Ltd. at rank #5,698 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in H01T (SPARK GAPS; OVERVOLTAGE ARRESTERS USING SPARK GAPS; SPARKING PLUGS; CORONA DEVICES; GENERATING IONS TO BE INTRODUCED INTO NON-ENCLOSED GASES). As a Foreign Corporation, Niterra Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Niterra sits between Lockheed Martin Energy, Llc (60 patents, rank #5,694) and Open Text S.a. (60 patents, rank #5,702) - the closest US assignees by grant volume. The composite Innovation Score of 60.1/100 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. Historical data spans 2023 through 2025, with 60 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. Niterra Co., Ltd.'s 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Niterra 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.
