Portfolio overview

Guangdong Sirui Optical Co., Ltd. has been granted 33 US utility patents between 2019 and 2025, placing Guangdong Sirui Optical Co., Ltd. at rank #9,507 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. The composite Innovation Score of 36.2/100 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 30 grants, compared with 3 in the 2015–2019 window, a +900% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Guangdong Sirui Optical Co., Ltd.'s 8.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangdong Sirui Optical Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Guangdong's 33 grants land it in the top 47% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Guangdong ranks #9,507 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G03B - see who else leads that technology area. G03B leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
