Original assignee

The original assignee named on the issued patent is CM HK Ltd.

CM HK Ltd, or China Mobile Hong Kong Company Limited, is a major telecommunications operator in Hong Kong and a wholly-owned subsidiary of China Mobile. They offer a wide range of products and services, including mobile communication, internet services, broadband, and various smart-home products and accessories such as mobile phones, Wi-Fi routers, keyboards, and mice. They were the first to launch Personal Communications Services (PCS) in Hong Kong in 1997 and are currently the largest telecommunications operator in the region.

Given their extensive product lines including smartphones and various electronic devices, it is highly probable that CM HK Ltd ships products embodying the claims of US 11698687, which pertains to an electronic device for motion detection (e.g., pointing devices, smartphones, navigation equipment).

CM HK Ltd is currently an operating company.

NPE / troll-pattern signals

1. Shell-entity transfer — unclear. The entities "CYWEEMOTION HK LIMITED" and "CYWEE GROUP LTD." transferred the patent to "CM HK LIMITED". While "LIMITED" in a company name is common, without information on their product lines, business activities, or registered agent addresses, it cannot be determined if these were shell entities. The patent was originally filed by CM HK Ltd, which is an operating company, and the transfers appear to be a consolidation back to "CM HK LIMITED" (likely the same or closely related entity).
2. Known asserter in the chain — not present. CM HK Ltd is a large operating telecommunications company. There is no indication from the provided information that CM HK Ltd, CYWEEMOTION HK LIMITED, or CYWEE GROUP LTD. are known NPEs.
3. Repeat correspondent across the chain — not present. Correspondent information (attorney name, firm, address) is not provided in the source text, so this signal cannot be evaluated.
4. Cascading transfers — present. There are two reassignments to CM HK LIMITED on consecutive days (2024-09-25 and 2024-09-26). This timing indicates a rapid sequence of transfers.
5. Pre-litigation transfer — unclear. The reassignments occurred in September 2024. District court cases (e.g., in Texas Eastern District Court, 2:24-cv-00880) were also filed in 2024. Without the exact filing dates of the lawsuits, it is unclear if these transfers occurred within 6 months prior to the litigation.
6. Bankruptcy fire-sale — not present. There is no mention of bankruptcy for any of the entities involved.
7. Privateering — not present. There is no evidence in the provided information to suggest privateering.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

Operating-company assertion

The patent was originally filed by CM HK Ltd, which is a large operating telecommunications company that ships products likely embodying the claims. Although there are two rapid reassignments in September 2024 (2024-09-25 and 2024-09-26), these appear to be internal reorganizations or consolidations to CM HK LIMITED (likely the same or a closely related operating entity) from other entities within the same corporate sphere, rather than transfers to a separate licensing entity. While litigation is active, the primary owner is an operating company.
