Inventors

  • G. Victor Treyz: At the time of filing, likely employed by Onetta, Inc., as the patent was assigned to Onetta, Inc. on the filing date.
  • Jun Ye: At the time of filing, likely employed by Onetta, Inc., as the patent was assigned to Onetta, Inc. on the filing date.

Original assignee

Onetta Inc.
Onetta Inc. was a company focused on optical networking equipment, specifically optical amplifiers with advanced monitoring and dynamic spectral filtering capabilities for wavelength-division multiplexing (WDM) systems. The patent itself describes equipment for use in fiber-optic communications networks, including optical channel monitors and dynamic spectral filters, suggesting Onetta Inc. shipped products embodying these claims. Onetta Inc. was acquired by Bookham Technology PLC (later Bookham Inc.) in 2006, meaning its current status as an independent entity is dissolved.

  5. Pre-litigation transfernot present. No litigation involving this patent has been identified.
  6. Bankruptcy fire-salenot present. The transfer from Onetta Inc. to Bookham Technology PLC was due to an acquisition, not a bankruptcy proceeding.
  7. Privateeringnot present. There is no evidence to suggest this was a privateering arrangement; it appears to be a standard acquisition.

Verdict

Insufficient data

The recorded assignment history for US 6529316 does not show any typical NPE or patent troll patterns. The transfers reflect a standard acquisition by an operating company (Onetta Inc. to Bookham Technology PLC, recorded 2006-08-01, Reel 018092/0971). The patent has since expired due to fee-related reasons, indicating it is no longer enforceable.
