1 case as defendant.
Dialect LLC is a non-practicing entity (NPE) that focuses on patent monetization, primarily asserting an acquired portfolio of patents. While its headquarters and founding year as a distinct entity for patent assertion are not publicly disclosed, the company is associated with familiar figures in patent monetization. There are other unrelated companies also named "Dialect," including a creative agency, a consulting firm, and a real estate advisor.
Dialect LLC's operations center on licensing and asserting patents related to natural language processing (NLP), speech recognition, natural language human-machine interactions, and conversational AI methods. The asserted patent portfolio originated from Voicebox Technologies, a pioneer in natural language processing that was acquired by Nuance Communications in 2018. The patents cover technologies such as processing and responding to natural language inputs and using context-specific domain agents for spoken queries.
As an NPE, Dialect LLC's patent litigation posture is that of a plaintiff asserting its acquired portfolio against operating companies. Although the provided case data shows one defendant case at the Patent Trial and Appeal Board (PTAB) and no plaintiff cases, external searches reveal that Dialect LLC has actively filed numerous patent infringement lawsuits as a plaintiff against major technology companies. These defendants include Samsung, Amazon, Meta Platforms, Microsoft, and Google, with suits often filed in plaintiff-friendly venues such as the Eastern District of Texas.
A notable case in the company's litigation history is Unified Patents LLC v. Dialect LLC, the sole tracked case, which is a PTAB proceeding where Unified Patents, an anti-NPE organization, challenges the validity of Dialect's patents. Unified Patents has initiated multiple ex parte reexamination proceedings against Dialect's natural language patents, with some claims being found invalid or facing final rejection. Additionally, in a lawsuit against Amazon, at least six of Dialect's seven asserted patents related to speech recognition technology were ruled as not meeting patent eligibility criteria under 35 U.S.C. § 101. Some of Dialect's district court cases against tech giants have also seen venue transfers, such as the case against Meta moving to the Western District of Washington and against Google to California.
Unified Patents LLC filed an Inter Partes Review (IPR) against Dialect LLC at the Patent Trial and Appeal Board concerning patent 7917367, which resulted in a settlement.
