What this shows Guangdong Sirui Optical Co., Ltd. stamps GRANTS-SMALL, UPPER-Q, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-PAR, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #9,506 of 50,000; Innovation Score 36.2/100 sits in the top 47% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Ginkgo Bioworks, Inc. (±0 grants).
Guangdong Sirui Optical Co., Ltd. has been granted 33 US utility patents between 2019 and 2025, placing Guangdong Sirui Optical Co., Ltd. at #9,506 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in G03B (APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR). As a Foreign Corporation, Guangdong Sirui Optical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangdong sits between Ginkgo Bioworks, Inc. (33 patents, rank #9,503) and Haver & Boecker OHG (33 patents, rank #9,511) - the closest US assignees by grant volume. The composite Innovation Score of 36.2/100 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 27 grants, compared with 3 in the 2015–2019 window, a +800% 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. Guangdong Sirui Optical Co., Ltd.'s 8.7 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.
