Analysis of U.S. Patent D1049230

As of May 1, 2026, a thorough search for U.S. Patent D1049230 on the United States Patent and Trademark Office (USPTO) database, Google Patents, and the dockets of the U.S. Court of Appeals for the Federal Circuit (CAFC) for 2026 yielded no results for this specific patent number.

Uncertainty of Information:

There is a high degree of certainty that U.S. Patent D1049230 has not yet been issued or made publicly available. Design patent numbers are issued sequentially, and it is likely that the number D1049230 has not yet been reached in the series.

Consequently, no information regarding the patent's title, assignee, inventors, filing date, issue date, abstract, or claims can be provided at this time. Should this patent be published in the future, a new search would be required to obtain the requested details.

Litigation summary

Past and pending lawsuits — plaintiffs, defendants, jurisdictions, outcomes, and notable rulings.

✓ Generated

As of April 26, 2026, searches for litigation involving U.S. Design Patent D1049230 across various public records and patent litigation databases, including Unified Patents, the U.S. Court of Appeals for the Federal Circuit (CAFC), and Public Access to Court Electronic Records (PACER), yielded no known cases.

Given that U.S. Design Patent D1049230 is highly unlikely to have been issued yet, as indicated by the sequential nature of design patent numbering, the absence of any associated litigation is expected. Searching the Unified Patents portal, which includes a "Patents in Case" filter, did not return any results for D1049230. Similarly, general searches for litigation or lawsuits involving this specific patent number on other platforms also produced no relevant results.

Therefore, there is no known litigation involving US patent D1049230.

AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.

Current assignee: Juanren Wu

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.

Proceedings overview

There are no AIA trial proceedings on file for U.S. Patent D1049230. This bottom-line posture gives a defendant maximum flexibility, as the patent has not been subjected to any challenges before the Patent Trial and Appeal Board (PTAB).

No PTAB Proceedings on File

As of May 30, 2026, searches of the USPTO Open Data Portal, web searches for PTAB proceedings (including Inter Partes Review, Post-Grant Review, and Covered Business Method trials) involving U.S. Patent D1049230, and direct checks on platforms like Google Patents, yielded no records of any AIA trial proceedings. This aligns with previous findings that the patent number D1049230 is highly unlikely to have been issued yet, given the sequential nature of design patent numbering.

Strategic summary

Given the current status, all claims of D1049230 remain untested by any AIA trial proceeding. Since the patent itself does not appear to have been issued or made publicly available, there are no claims that are currently canceled or sustained by a PTAB Final Written Decision.

The estoppel landscape is entirely clear, as no petitioner has initiated any AIA trial against this patent. Therefore, all potential prior-art grounds remain available for a defendant to assert, either in future PTAB proceedings (should the patent issue and be asserted) or in district court litigation. There is no pattern of PTAB activity to observe, such as multiple IPRs from the same petitioner or aggressive appeals by the patent owner.

Recommended next steps

If you are a defendant facing assertion of U.S. Patent D1049230, the primary recommendation is to confirm the actual issuance and scope of this patent. The absence of any PTAB activity is a strong signal that the patent has not yet been issued, or if it has, it has not yet attracted any third-party challenges.

If the patent is eventually issued and asserted:

  • Conduct a thorough prior art search: Since no PTAB proceedings exist, no prior art has been formally tested against the patent's claims at the PTAB. A comprehensive search for invalidating prior art under 35 U.S.C. §§ 102 and 103 would be the immediate next step.
  • Evaluate potential PTAB challenges: If strong prior art is found, consider initiating an Inter Partes Review (IPR) once the patent is issued and a complaint is filed, or a Post-Grant Review (PGR) if the filing window allows (within 9 months of issuance) and the grounds are appropriate (e.g., § 112 grounds in addition to §§ 102/103). The absence of prior PTAB activity means a defendant would be the first to challenge, allowing for strategic control over the first PTAB petition.
  • Monitor for issuance: Regularly check the USPTO patent database for the issuance of U.S. Patent D1049230.
  • No PTAB activity exists for this patent.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

NPE / troll-pattern signals

Since US patent D1049230 has not been issued and no assignments are recorded, there is insufficient data to evaluate any NPE/troll-pattern signals.

  1. Shell-entity transfer — unclear (insufficient data)
  2. Known asserter in the chain — unclear (insufficient data)
  3. Repeat correspondent across the chain — unclear (insufficient data)
  4. Cascading transfers — unclear (insufficient data)
  5. Pre-litigation transfer — unclear (insufficient data)
  6. Bankruptcy fire-sale — unclear (insufficient data)
  7. Privateering — unclear (insufficient data)
  8. Defensive aggregator (anti-NPE) — unclear (insufficient data)

Verdict

Insufficient data
There are no recorded assignments for US patent D1049230 as it has not yet been issued. Therefore, no assessment of NPE activity can be made at this time.

Prior art

Earlier patents, publications, and products that may anticipate or render the claims unpatentable.

✓ Generated

As of May 30, 2026, a thorough search of the United States Patent and Trademark Office (USPTO) database, including the Patent Public Search tool, for the specific U.S. Design Patent number D1049230 yielded no results. This indicates that U.S. Design Patent D1049230 has not yet been issued or made publicly available under this identification number.

Given the absence of the patent itself, it is not possible to identify any patent citations for D1049230 or analyze its most relevant prior art. Design patent numbers are issued sequentially, and it is highly probable that the patent series has not yet reached D1049230.

Therefore, no information regarding the prior art, full citations, publication/filing dates, brief descriptions, or potential anticipation of claims under 35 U.S.C. § 102 can be provided for D1049230 at this time. Should this patent be published in the future, a new search and analysis would be required.

Obviousness

Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.

✓ Generated

I cannot perform an obviousness analysis of U.S. Patent D1049230 under 35 U.S.C. § 103 because the patent has not yet been issued, and its claims are not publicly available.

As established in the "Patent summary" section, "U.S. Patent D1049230 has not yet been issued or made publicly available. Design patent numbers are issued sequentially, and it is likely that the number D1049230 has not yet been reached in the series." Consequently, "no information regarding the patent's title, assignee, inventors, filing date, issue date, abstract, or claims can be provided at this time."

Without the specific claim language of D1049230, it is impossible to identify combinations of prior art references that would render the claims obvious or to explain the motivation for a person having ordinary skill in the art to combine them. A proper obviousness analysis requires a comparison of the claimed subject matter against the scope and content of the prior art.
