Portfolio overview
Xiamen Lota International Co., Ltd. has been granted 113 US utility patents between 2015 and 2025, placing Xiamen Lota International Co., Ltd. at rank #3,316 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in E03C (DOMESTIC PLUMBING INSTALLATIONS FOR FRESH WATER OR WASTE WATER ; SINKS). As a Foreign Corporation, Xiamen Lota International Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.8/100 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 95 grants, compared with 18 in the 2015–2019 window — a +428% 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. Xiamen Lota International Co., Ltd.'s 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xiamen Lota International Co., Ltd. against peers pursuing similar technology classes.
