Portfolio overview

Exergyn, Ltd. has been granted 63 US utility patents between 2015 and 2025, placing Exergyn, Ltd. at rank #5,437 across all assignees tracked by PlainPatent. This portfolio spans 77 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in F03G (SPRING, WEIGHT, INERTIA OR LIKE MOTORS; MECHANICAL-POWER PRODUCING DEVICES OR MECHANISMS, NOT OTHERWISE PROVIDED FOR OR USING ENERGY SOURCES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Exergyn, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Exergyn sits between Century Technology (shenzhen) Corporation Limited (63 patents, rank #5,433) and Guangdong Huanengda Electrical Appliances Co., Ltd (63 patents, rank #5,441) - the closest US assignees by grant volume. The composite Innovation Score of 55.3/100 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 36 grants, compared with 27 in the 2015–2019 window, a +33% 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. Exergyn, Ltd.'s 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 77 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Exergyn, 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.
