The inventors assigned their rights to OSRAM OPTO SEMICONDUCTORS GMBH on 2008-12-11 (Reel 062638/0911), which is the priority date of the patent. This indicates they were likely employed by OSRAM or a related entity at that time. There are no immediate unusual patterns, such as a mass departure of inventors, evident from the patent text or assignment records.

Original assignee

The first corporate entity to acquire rights from the inventors was OSRAM OPTO SEMICONDUCTORS GMBH (Reel 062638/0911). OSRAM is a well-known operating company primarily in the field of lighting and optoelectronics, shipping a wide range of products embodying various lighting technologies, including LEDs. OSRAM OPTO SEMICONDUCTORS GMBH is an active operating entity within the OSRAM group. The patent refers to "Organic-light emitting diode" technology, which aligns with OSRAM's product portfolio. The Google Patents entry lists "Pictiva Displays International Ltd" as the "Original Assignee," which refers to the entity that filed the application and ultimately held the rights at the time of publication of this specific grant, following a chain of assignments and a name change.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The patent was transferred from an operating company (OSRAM OLED GMBH) to "DOLYA HOLDCO 5 LIMITED" on 2023-10-23 (Reel 062638/0917), a generic-sounding holding company, which subsequently changed its name to PICTIVA DISPLAYS INTERNATIONAL LIMITED on the same date (Reel 062638/0914). This suggests a move to a licensing-focused entity.

2. Known asserter in the chain — Unclear. While PICTIVA DISPLAYS INTERNATIONAL LIMITED is not widely recognized on public NPE lists, the patent is currently subject to a PTAB IPR challenge (IPR2026-00129) initiated by Unified Patents. Unified Patents typically petitions to invalidate patents that are being asserted against its members, strongly implying that Pictiva Displays International Limited is engaging in assertion activities.

3. Repeat correspondent across the chain — Present. WILLIAM L. BAEHR of SCULLY, SCOTT, MURPHY & PRESSER, P.C. is listed as the correspondent for all four recorded assignments (Reel 062638/0911, Reel 062638/0920, Reel 062638/0917, Reel 062638/0914).

4. Cascading transfers — Present. Three assignments and one name change were executed on 2023-10-23 and recorded on 2023-10-24 (Reel 062638/0920, 062638/0917, 062638/0914). This rapid sequence of transfers, all within a single day of execution, is a strong indicator of a concerted effort to move the patent through a chain of entities.

5. Pre-litigation transfer — Present. The assignments to DOLYA HOLDCO 5 LIMITED and its subsequent name change to PICTIVA DISPLAYS INTERNATIONAL LIMITED were executed on 2023-10-23. Google Patents also notes "First worldwide family litigation filed" on 2023-10-23, the exact same date as these transfers and the filing date of the patent application. This direct contemporaneity strongly suggests the transfers were made in preparation for or concurrent with assertion activities.

6. Bankruptcy fire-sale — Not present. There is no indication in the assignment records or publicly available information that any assignor in the chain underwent bankruptcy proceedings leading to this transfer.

7. Privateering — Unclear. While the patent originated from an operating company (OSRAM) and was transferred to a holding company (Pictiva), there is no explicit public evidence (e.g., SEC filings or journalistic reports) confirming a privateering agreement where Pictiva asserts on OSRAM's behalf. However, the nature of the transfers is consistent with such an arrangement.

8. Defensive aggregator (anti-NPE) — Not present. The current assignee is PICTIVA DISPLAYS INTERNATIONAL LIMITED, and the patent is actively being challenged by Unified Patents, an anti-NPE organization. This indicates assertion, not defensive aggregation.

Verdict

NPE — high confidence. The chain exhibits multiple strong NPE signals: a shell-entity transfer from an operating company to a generic holding company that changed its name (Reel 062638/0917, 062638/0914), the same correspondent attorney appearing on all transfers (Reel 062638/0911, 062638/0920, 062638/0917, 062638/0914), cascading transfers within a single day of execution, and transfers executed concurrently with the filing of both the patent application and initial worldwide family litigation (2023-10-23). The subsequent IPR challenge by Unified Patents (IPR2026-00129) further supports the conclusion of assertion activity by the current assignee.
