Portfolio overview

Hangzhou Hpwinner OPTO Corporation has been granted 49 US utility patents between 2015 and 2025, placing Hangzhou Hpwinner OPTO Corporation at #6,784 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.7 claims per patent with primary concentration in F21V (FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Hangzhou Hpwinner OPTO Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Georgia-pacific Gypsum Llc (49 patents, rank #6,780) and IMS GEAR SE & Co. KGAA (49 patents, rank #6,788) - the closest US assignees by grant volume. The composite Innovation Score of 31.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 15 grants, compared with 32 in the 2015–2019 window, a -53% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Hangzhou Hpwinner OPTO Corporation's 5.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 15 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
