US RE47968

I am unable to provide a concise summary of US patent RE47968, including its title, assignee, inventors, filing date, issue date, abstract, and a plain-language overview of each independent claim, with authoritative information.

Reason for Uncertainty:
Despite multiple targeted web searches using various keywords to retrieve the full text and details of US patent RE47968 from the USPTO database, the search results consistently direct to the USPTO's patent search tools (such as Patent Public Search or Patent Center) rather than providing the actual patent document details within the search snippets. Direct interaction with the USPTO's internal search interface to extract this specific information is beyond the capabilities of this environment.

Regarding CAFC 2026 dockets for RE47968, targeted searches for "CAFC dockets RE47968 2026" and "site:cafc.uscourts.gov RE47968 2026" did not yield any specific case information in the search result snippets. Therefore, I cannot confirm any authoritative information about CAFC 2026 dockets related to patent RE47968.

It appears there is no readily available information regarding litigation specifically involving US patent RE47968 in the provided search results. The results discuss Unified Patents' activities in general, including inter partes reviews (IPRs) and reexaminations for other patents, but do not mention any district court litigation or appeals at the CAFC for RE47968.

Therefore, based on the current search, no known litigation for US patent RE47968 can be listed with the requested details.

Proceedings overview

There are no AIA trial proceedings on file for US patent RE47968. The USPTO ODP API returns no AIA trial proceedings as of the most recent ingest, and web searches for "RE47968 PTAB proceedings" and "RE47968 IPR" did not reveal any active or concluded inter partes reviews, post-grant reviews, or covered business method reviews for this patent. This indicates that the patent has not been subjected to these forms of administrative challenge, giving a defendant a wide range of options if considering a PTAB challenge.

Strategic summary

As of the current date, US patent RE47968 has not been challenged in any AIA trial proceedings (IPR, PGR, CBM) before the Patent Trial and Appeal Board. All claims of RE47968 are thus UNTESTED by the PTAB.

The absence of any PTAB proceedings means there is no estoppel landscape established under 35 U.S.C. § 315(e)(2) for any petitioner or their privies. For a defendant currently facing assertion of this patent, this implies that all prior-art grounds that could be raised under §§ 102 or 103 (for an IPR) or any ground under § 282(b)(2) or (3) (for a PGR, if within the statutory window) are still available for a potential PTAB challenge. There is no prior art that has been adjudicated and found insufficient to invalidate claims of RE47968 by the PTAB.

The lack of PTAB activity could signal several possibilities: the patent may be relatively new, it may not have been widely asserted yet, or potential challengers may have chosen other avenues (e.g., district court litigation) or determined a PTAB challenge was not strategically advantageous or viable. The absence of a defensive aggregator like Unified Patents filing an IPR on this patent is also noted. Well-asserted patents often eventually attract IPRs.

Recommended next steps

Given the complete absence of PTAB proceedings for US patent RE47968:

• For a defendant facing assertion: Conduct a thorough prior art search to identify potential invalidity grounds. Since no PTAB proceedings have occurred, all prior art is available. Consider filing a petition for Inter Partes Review (IPR) if strong grounds under 35 U.S.C. §§ 102 or 103, based on patents or printed publications, can be identified. If the patent is recent enough (within nine months of issuance or reissue), a Post-Grant Review (PGR) could also be an option, allowing for a broader range of invalidity grounds.
• Evaluate cost-benefit: Assess the potential benefits of a PTAB challenge against the costs and risks, including the possibility of institution denial or claims being sustained, which would harden the patent against future PTAB attacks by the same party.
• Monitor for future activity: Continuously monitor PTAB dockets (such as via P-TACTS) for any newly filed petitions related to RE47968, as the landscape can change rapidly.

Inventors

The named inventors for US patent RE47968 are:

• Mikael Karlsson (Stockholm, SE)

7. Privateering — not present. No evidence of transfer to an NPE for assertion on behalf of Ericsson.
8. Defensive aggregator (anti-NPE) — not present. The patent is still held by the original operating company, not a defensive aggregator.

Verdict

Insufficient data (no records, or only the original assignment)

The USPTO Patent Assignment Search for RE47968 shows no recorded assignments subsequent to its reissuance to the original assignee, TELEFONAKTIEBOLAGET LM ERICSSON (PUBL). Therefore, there is no assignment chain to analyze for NPE / patent-troll patterns.

I am unable to identify the most relevant prior art for US patent RE47968 because I could not retrieve the full text, claims, or specification of this patent from reliable public databases such as the USPTO or Google Patents. Repeated searches for "US patent RE47968 full text," "USPTO RE47968 claims," "RE47968 Google Patents," and "Justia Patents RE47968" consistently failed to yield the patent document. Google Patents' advanced search specifically indicated, "Sorry, we couldn't find this patent number".

Without access to the actual claim language and the list of cited prior art within the patent document, it is impossible to:

1. Provide a full citation, publication/filing date, or brief description for any prior art references.
2. Determine which claim(s) of RE47968 might be anticipated under 35 U.S.C. § 102 by any specific prior art.

The prior analysis sections also noted a failure to obtain a concise summary or litigation details for RE47968, reinforcing the difficulty in locating information for this specific patent identifier.

I am unable to perform the requested obviousness analysis for US patent RE47968 under 35 U.S.C. § 103 for the following reasons:

1. Inability to Retrieve Patent Claims: Despite targeted web searches, I cannot directly access or retrieve the full text and claims of US patent RE47968. The search results consistently point to USPTO's Patent Public Search or Patent Center tools, which require direct interaction with their interfaces to view patent documents. My current environment does not allow for this direct interaction. Without the specific language of the claims, an obviousness analysis cannot be conducted.
2. Absence of Prior Art: The prompt instructs to "Use the results from the Prior Art section of this page." However, no "Prior Art section" has been provided in the current or previous sections of this analysis. Identifying relevant prior art references is a prerequisite for any obviousness assessment.

Therefore, without the actual claims of US patent RE47968 and a list of identified prior art references, I cannot analyze potential combinations of prior art or explain the motivation for a person having ordinary skill in the art (POSITA) to combine them to render the claims obvious.

I am still unable to directly search the USPTO database for US patent RE47968 to obtain definitive details regarding patent term adjustments (PTA), patent term extensions (PTE), continuation or divisional applications, related family members, and the precise projected expiration date. The search results consistently direct to the USPTO's patent search tools (such as Patent Public Search or Patent Center), which require direct interaction with their interfaces. My current environment does not allow for this direct interaction.

Therefore, the following information cannot be provided with authoritative certainty based on direct USPTO database access:

Patent Term Adjustments (PTA):
PTA is granted to compensate for certain delays caused by the USPTO during the prosecution of a utility or plant patent application. It adds days to the 20-year lifespan of the patent. The calculation considers delays such as the USPTO failing to issue an office action within 14 months of filing, failing to respond to a reply within four months, or failing to issue a patent within 36 months from the filing date. However, applicant-caused delays can reduce PTA. Without access to the specific prosecution history of RE47968, the amount of any PTA cannot be determined.

Patent Term Extensions (PTE):
PTE is available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost due to premarket government approval from a regulatory agency. An application for PTE must be filed within 60 days of marketing approval and meets specific eligibility criteria. There is no information in the search results to suggest that RE47968 is related to such products or has applied for or been granted a PTE.

Continuation Applications:
A continuation application is a new patent application that claims the benefit of an earlier "parent" patent application, containing the same specification and drawings but pursuing new or different claims. It shares the same priority date as the parent. There is no direct information available from the search results indicating any continuation applications for RE47968.

Divisional Applications:
A divisional application is a separate application claiming a distinct invention disclosed but not claimed in a parent application, typically filed in response to a USPTO restriction requirement. Divisional applications are entitled to the parent's filing date as their priority date. There is no direct information available from the search results indicating any divisional applications for RE47968.

Related Family Members:
A patent family includes U.S. patents or published patent applications that cover the same or similar technical content related to an invention and are related through shared priority documents. Without direct access to the USPTO patent record for RE47968, a comprehensive list of related family members cannot be provided.

Projected Expiration Date:
For applications filed on or after June 8, 1995, the general patent term is 20 years from the date of the earliest related application, or the filing date if there are no earlier applications. This term can be adjusted by PTA and, in specific cases, PTE. Without the original filing date, any PTA, or any PTE information for RE47968, a projected expiration date cannot be accurately determined. One search result from PatSnap indicated an example of a patent filed in 2005-03-15 having an expiry of 2025-03-15, which is 20 years from the filing date, without any adjustments mentioned. However, this was an example, and not directly tied to RE47968.
