Across all tracked assignees
USPTO PatentsView assignee record - 6 granted patents across 10 technology areas, active 2024–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;).
The verdict
EM holds 6 US patents across 10 technology areas, rank #39,968 of 50,000 tracked assignees.
EM Coretech Inc. has been granted 6 US utility patents between 2024 and 2024, placing EM Coretech Inc. at rank #39,968 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, EM Coretech Inc. is one of the more focused assignees in the PatentsView dataset. By volume, EM sits between Elifeconnection Co., Ltd. (6 patents, rank #39,964) and ENCO Electronic Systems, Llc (6 patents, rank #39,972) - the closest US assignees by grant volume. The composite Innovation Score of 43.2/100 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. Historical data spans 2024 through 2024, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. EM Coretech Inc.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EM Coretech Inc. against peers pursuing similar technology classes.

How to use this portfolio
EM's 6 grants land it in the top 29% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
