Portfolio overview

Panasonic Liquid Crystal Display Co., Ltd. has been granted 597 US utility patents between 2015 and 2023, placing Panasonic Liquid Crystal Display Co., Ltd. at rank #769 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 claims per patent with primary concentration in G02F (OPTICAL DEVICES OR ARRANGEMENTS FOR THE CONTROL OF LIGHT BY MODIFICATION OF THE OPTICAL PROPERTIES OF THE MEDIA OF THE ELEMENTS INVOLVED THEREIN; NON-LINEAR OPTICS; FREQUENCY-CHANGING OF LIGHT; OPTICA). As a Foreign Corporation, Panasonic Liquid Crystal Display Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Panasonic sits between Vitesco Technologies Gmbh (601 patents, rank #765) and Schott Ag (594 patents, rank #773) - the closest US assignees by grant volume. The composite Innovation Score of 52.5/100 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 182 grants, compared with 415 in the 2015–2019 window, a -56% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Panasonic Liquid Crystal Display Co., Ltd.'s 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Panasonic Liquid Crystal Display Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Panasonic's 597 grants land it in the top 10% 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 #769 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G02F - see who else leads that technology area. G02F 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.
