ONE-E-WAY, INC. v. Sony Corporation et al.

The patent infringement litigation, ONE-E-WAY, INC. v. Sony Corporation et al. (ITC Inv. No. 337-TA-943), involves ONE-E-WAY, INC., a Pasadena-based "wireless audio innovator" that designs and manufactures headphones and accessories, founded by C. Earl Woolfork in 2004. While ONE-E-WAY describes itself as a company committed to commercializing its inventions, it also explicitly states that it "has been able to sustain itself through successful litigation and licensing efforts with major international electronics companies," including some of the defendants in this case, suggesting a hybrid or patent assertion entity (PAE) model. The defendants, Sony Corporation, BlueAnt Wireless, Creative Technology Ltd., and GN Netcom A/S, are established consumer electronics companies that produce and import wireless audio devices.

The core of the dispute centers on U.S. Patent No. 9,107,000, which generally describes a wireless digital audio system designed for private listening without interference. This system includes a portable audio source, a digital audio transmitter, and an audio receiver coupled to headphones, utilizing Code Division Multiple Access (CDMA) communication and fuzzy logic for optimized digital signal processing. The accused products are various wireless headphones and related audio systems imported by the defendants, which allegedly incorporate the technology covered by the asserted patent, particularly in providing private wireless audio.

The case is proceeding in the U.S. International Trade Commission (ITC), a forum known for its accelerated procedural schedule and powerful remedy of exclusion orders, which can prevent infringing products from entering the United States. An initial determination by the ITC found the asserted patents invalid based on the claim term "virtually free from interference" being indefinite. However, this crucial finding was reversed by the U.S. Court of Appeals for the Federal Circuit on June 12, 2017, in One-E-Way, Inc. v. International Trade Commission, No. 16-2105, which clarified that the term meant "free from eavesdropping" when viewed in light of the patent's specification and prosecution history, thereby reviving the case and remanding it back to the ITC for further proceedings. This Federal Circuit reversal is particularly notable as it re-established the enforceability of the patent claims against the accused consumer electronics products.

The litigation of ONE-E-WAY, INC. v. Sony Corporation et al., ITC Case No. 337-TA-943, involved a complaint alleging patent infringement related to wireless headset technology.

Here's a chronological overview of the key legal developments and outcome:

• 2015-01-13 – Investigation Initiated: The U.S. International Trade Commission (ITC) instituted Investigation No. 337-TA-943, titled "Certain Wireless Headsets," based on a complaint filed by One-E-Way, Inc.. The complaint alleged violations of Section 337 of the Tariff Act of 1930 through the importation and sale of certain wireless headsets infringing claims of U.S. Patent Nos. 7,865,258 (the "'258 patent") and 8,131,391 (the "'391 patent"). The respondents named in the investigation included Sony Corporation, Sony Corporation of America, Sony Electronics, Inc., BlueAnt Wireless Pty., Ltd., BlueAnt Wireless, Inc., Creative Technology Ltd., Creative Labs, Inc., and GN Netcom A/S d/b/a Jabra.

  • Note on Patent Discrepancy: The patent listed in the case metadata (9107000) does not appear in the available public records as one of the asserted patents in this specific ITC investigation and subsequent Federal Circuit appeal. The records consistently refer to U.S. Patent Nos. 7,865,258 and 8,131,391.

• 2016-05-12 – Initial Determination of Patent Invalidity: The ITC affirmed with modifications an Initial Determination (Order No. 17) that granted the respondents' motion for summary determination, finding the asserted patent claims invalid due to indefiniteness. Specifically, the ITC found the claim term "virtually free from interference" to be indefinite. As a result, the Commission found no violation of Section 337 and terminated the investigation.

• Claim Construction (Implicit from Appeal): The ITC's decision on indefiniteness necessarily involved a claim construction analysis that led to the finding that the term "virtually free from interference" lacked reasonable certainty.

• Discovery: While specific milestones are not publicly detailed, ITC investigations feature a very fast-paced discovery process, typically completing fact discovery within seven months of institution.

• 2017-06-12 – Federal Circuit Reversal and Remand: One-E-Way, Inc. appealed the ITC's decision. The U.S. Court of Appeals for the Federal Circuit reversed the ITC's finding of indefiniteness. The Federal Circuit concluded that the term "virtually free from interference," when properly interpreted in light of the patent specification and prosecution history, would inform a person of ordinary skill in the art about the scope of the invention with reasonable certainty. The case was then remanded back to the ITC for further proceedings consistent with the Federal Circuit's ruling. This effectively revived the investigation.

• 2018-08-15 – Partial Termination via Settlement: Following the Federal Circuit's remand, the ITC determined not to review an Initial Determination (Order No. 28) which granted a joint motion to terminate the remand investigation as to respondents BlueAnt Wireless Pty., Ltd. and BlueAnt Wireless, Inc. This termination was based on a settlement agreement reached between One-E-Way, Inc. and the BlueAnt respondents.

• Current Posture: While the initial prompt indicates the case is "Active," the last public record found for 337-TA-943 is the partial termination with BlueAnt Wireless in August 2018. There are no subsequent public records or news reports indicating ongoing litigation or a final determination regarding the remaining respondents (Sony Corporation, Creative Technology Ltd., GN Netcom A/S) since the Federal Circuit's remand in 2017. This strongly suggests that the remaining aspects of the investigation likely concluded through further settlements or other forms of termination not widely publicized, as is common in ITC proceedings.

• Parallel PTAB Proceedings: No public records were found indicating any parallel Inter Partes Review (IPR) or Post-Grant Review (PGR) proceedings before the Patent Trial and Appeal Board (PTAB) specifically challenging U.S. Patent Nos. 7,865,258 or 8,131,391 in relation to this ITC investigation. The ITC generally proceeds quickly and rarely stays its investigations pending IPRs.

Based on the Federal Circuit's opinion in One-E-Way, Inc. v. International Trade Commission, which reversed an initial ITC finding and revived the case (No. 16-2105, decided June 12, 2017), the plaintiff, ONE-E-WAY, INC., was represented by the following counsel:

• Douglas Glen Muehlhauser

  • Role: Lead Counsel (argued for appellant)

Defendant Counsel in ONE-E-WAY, INC. v. Sony Corporation et al. (337-TA-943)

The ITC investigation 337-TA-943, concerning "Certain Wireless Headsets," named Sony Corporation, BlueAnt Wireless, Creative Technology Ltd., and GN Netcom A/S as defendants. While the prompt lists the case as "Active," public records indicate that the investigation has been terminated as to all respondents following a reversal and remand by the Federal Circuit.

Initially, the ITC found the asserted patents invalid in 2015, leading to the termination of the investigation in May 2016. However, the Federal Circuit reversed this finding and remanded the case on June 12, 2017, thereby "reviving the case." During the subsequent remand proceedings:

• Sony Corporation and Creative Technology Ltd. were terminated from the remand investigation on February 26, 2018, and June 26, 2018, respectively.
• BlueAnt Wireless was terminated on August 1, 2018, based on a settlement agreement.
• GN Netcom A/S was the "last-remaining respondent" on remand and was also terminated based on a settlement agreement, resulting in the investigation being "terminated in its entirety." The specific date of this final termination after August 2018 is not immediately available in the provided public snippets.

Given the termination of all defendants on remand, the following counsel information pertains to their representation during the active phases of the investigation, including the initial proceedings and the remand period, up to their respective settlements and terminations. Due to the limitations of public web searches without direct access to the ITC's Electronic Document Information System (EDIS), specific attorney roles (lead, of counsel, local, in-house) and detailed one-line notes on experience are challenging to definitively ascertain for all attorneys. However, the firms involved in ITC Section 337 investigations are often prominent intellectual property litigators.

Efforts to identify specific counsel of record through public web searches against PACER, docket sheets, firm websites, court opinions, Law360, and Reuters Legal for this specific ITC investigation did not yield a comprehensive list of individual attorneys and their roles for each defendant. Legal news and firm websites often highlight general ITC experience rather than specific attorneys on particular older cases without a direct search by case number on subscription databases. Therefore, specific counsel names for each defendant are not definitively sourced, but the typical representation in such cases involves specialized ITC litigation firms.

Based on general practices in ITC Section 337 cases, defendants typically retain law firms with strong intellectual property and international trade litigation experience. For an active case, such information would be found in notices of appearance on the ITC's docket. Without direct access to the full docket entries for 337-TA-943, specific names and firms for each defendant are not publicly available through the general search methods employed.

Therefore, at this time, the specific counsel of record representing each of the defendant(s) with their roles, firms, and detailed experience cannot be definitively identified through public web search. Filings containing this information were not readily accessible or summarized in the provided search results.
