US8521927B2 — System and method for text entry


If your company develops, manufactures, or licenses products with text entry functionality — including mobile devices, tablets, embedded systems, or software keyboards — US8521927B2 warrants a freedom-to-operate assessment. The patent was asserted against a major device OEM and remains unadjudicated following a without-prejudice dismissal. R&D and product teams shipping new text input features or entering the mobile input market should prioritise this review.
Official order — verbatim text
The court order records a straightforward Rule 41(a)(1)(A)(i) voluntary dismissal without prejudice, accepted and acknowledged by the court on Televo's notice alone. No substantive findings were made: no infringement, validity, or claim construction rulings appear in the record. The dismissal without prejudice preserves Televo's right to refile and affords Kyocera no preclusive protection on the merits.
Dismissed without prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff's right to voluntarily dismiss
Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. Here, the Court accepted and acknowledged Televo's notice, and dismissed all claims without prejudice. This is a procedural exit — no merits adjudication occurred.
No merits rulingWithout prejudice: the refiling door remains open
A dismissal without prejudice does not bar Televo from reasserting the same patent claims against Kyocera in a future action, subject to applicable statutes of limitations and any other procedural constraints. This contrasts with a dismissal with prejudice, which would permanently extinguish the claims. The public record is silent on any conditions attached to this dismissal.
Refiling possibleKyocera escapes judgment — but uncertainty persists
Kyocera Corp. obtains no formal adjudication in its favour. While the immediate litigation burden is lifted, a without-prejudice dismissal provides no res judicata protection. Kyocera remains exposed to a potential refiling by Televo asserting the same US8521927B2 patent. No invalidity finding or non-infringement ruling was made on the public record.
No res judicata shieldText entry patent remains active and unlitigated to judgment
US8521927B2 has not been adjudicated invalid or found unenforceable. Device manufacturers, software developers, and others operating in the text input or mobile interface space who have not assessed exposure to this patent should note that Televo retains the right to enforce it. The specific commercial terms of any resolution, if any exist, are not disclosed in the available record.

Televo LLC's enforcement footprint around US8521927B2
Televo LLC's assertion of US8521927B2 against a major device OEM suggests an active enforcement strategy in the text entry space. Monitoring Televo's broader patent holdings — including any continuations, divisionals, or related applications in the US11/774578 family — can reveal the full scope of potential exposure for device and software companies in this domain.
PAE portfolio watchFiling trends in text entry and keyboard input technology
The text entry and on-screen keyboard space has seen sustained patent filing activity from both device OEMs and specialised IP holders. Tracking recent filing trends in predictive text, gesture input, and keyboard software patents can surface competitive risks and white-space opportunities for product and R&D teams developing next-generation input methods.
Input method IP trendsKyocera's patent position in text input and mobile interfaces
As a mobile device and communications equipment manufacturer, Kyocera holds its own patent portfolio in hardware and software interface technologies. Analysing Kyocera's defensive filings and cross-licensing activity in the text entry and input method domain can inform competitive intelligence and identify areas where the company is building IP protection for future products.

Portfolio viewWhat this case signals for the text entry and mobile input IP landscape
A voluntary early dismissal in E.D. Texas without prejudice leaves the enforcement posture of US8521927B2 unresolved — and potentially in play.
Without-prejudice dismissal signals unresolved enforcement risk
Televo's decision to voluntarily dismiss before any substantive ruling means US8521927B2 remains unadjudicated. Companies developing or commercialising text entry or keyboard input technologies should treat this patent as an active enforcement risk until a merits ruling or expiry removes the uncertainty.
E.D. Texas remains a preferred venue for PAEs asserting input method patents
The Eastern District of Texas is a consistently favoured forum for patent assertion entities. The filing of this case — and the speed of its dismissal — is consistent with a litigation strategy that may include settlement discussions, licensing approaches, or portfolio-level negotiations that do not surface on the public docket.
Kyocera's exposure to US8521927B2 may not be fully resolved
Without a consent judgment or covenant not to sue on the record, Kyocera's freedom to operate with respect to US8521927B2 is not publicly confirmed. Competitors and supply chain partners of Kyocera in the mobile and communications device space should monitor for any refiling or related enforcement activity by Televo.
Televo's portfolio strategy: mapping adjacent text input patent filings
Patent assertion entities asserting text entry or input method patents often hold or acquire related continuation and divisional patents. A thorough portfolio search around US8521927B2 — including continuation families and related application no. US11/774578 — is advisable for any company with text input functionality in its products.
