Portfolio overview

Panasonic Ecology Systems Guangdong Co., Ltd has been granted 48 US utility patents between 2015 and 2024, placing Panasonic Ecology Systems Guangdong Co., Ltd at #6,937 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a Foreign Corporation, Panasonic Ecology Systems Guangdong Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Panasonic sits between Openet Telecom Ltd. (48 patents, rank #6,935) and Quixey, Inc. (48 patents, rank #6,943) - the closest US assignees by grant volume. The composite Innovation Score of 37.7/100 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 10 grants, compared with 38 in the 2015–2019 window, a -74% 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. Panasonic Ecology Systems Guangdong Co., Ltd's 10.6 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 20 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio

Panasonic's 48 grants land it in the top 43% 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 - Panasonic ranks #6,937 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F24F - see who else leads that technology area. F24F 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.
