What this shows OPTO TECH Corp. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-DROP, BOOK-FULL. Volume places it #20,201 of 50,000; Innovation Score 32.9/100 sits in the top 57% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is OIL Crops Research Institute, Chinese Academy OF Agricultural Sciences (±0 grants).
OPTO TECH Corp. has been granted 14 US utility patents between 2015 and 2023, placing OPTO TECH Corp. at #20,201 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.4 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, OPTO TECH Corp. is one of the more focused assignees in the PatentsView dataset. By volume, OPTO sits between OIL Crops Research Institute, Chinese Academy OF Agricultural Sciences (14 patents, rank #20,185) and Osaka GAS Chemicals Co., Ltd. (14 patents, rank #20,193) - the closest US assignees by grant volume. The composite Innovation Score of 32.9/100 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 5 grants, compared with 9 in the 2015–2019 window, a -44% 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. OPTO TECH Corp.'s 12.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 11 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
