Portfolio overview

Xcelsis Corporation has been granted 44 US utility patents between 2019 and 2023, placing Xcelsis Corporation at #7,508 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a US Corporation, Xcelsis Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Xcelsis sits between Wenzhou Furuisi Building Materials Co., Ltd. (44 patents, rank #7,504) and Affera, Inc. (43 patents, rank #7,512) - the closest US assignees by grant volume. The composite Innovation Score of 39.9/100 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 42 grants, compared with 2 in the 2015–2019 window, a +2000% 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 US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Xcelsis Corporation's 19.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 15 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

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.
