Untitled case

The case is likely very recent, which explains why direct searches for "CAFC 26-1485" did not yield specific party names or details from news articles. The "Critical" status might indicate an expedited appeal or a significant underlying issue not yet public.

I will focus on the patent US9860450B2 to identify its owner and technical details, and then search for any litigation associated with it. The Unified Patents search is a good resource for this, as they track PTAB cases and district court litigation involving various patents. The USPTO patent search and assignment center are also key to getting basic patent information.

Refined Plan:

1. Patent Abstract & Technical Sketch (US9860450B2): Use USPTO Patent Public Search to find the abstract and a concise technical description.
2. Patent Owner/Assignee (US9860450B2): Use the USPTO Assignment Center or other patent databases to determine the current owner of the patent.
3. Litigation History of US9860450B2: Specifically search RPX and Unified Patents portals for any district court or PTAB cases related to this patent. This is the most promising route to uncover the parties and the originating district court case number if one exists that led to the CAFC appeal.
4. Connect to CAFC 26-1485: If a relevant district court case is found, I will try to link it to the CAFC 26-1485 appeal, or confirm if the patent is indeed the subject of this appeal.

Given the current date (May 29, 2026) and the case number (26-1485), it's highly probable that this is a recent appeal. If no direct litigation history or CAFC case details are immediately available, I will state that the information is not publicly accessible at this time.

Let's execute the refined plan.
The information gathered so far did not directly reveal the parties or the underlying district court case for CAFC 26-1485. The search results for the case number primarily referred to general CAFC news and procedures, or other recent CAFC opinions that do not match the case number 26-1485. This suggests that the case is either too new for public reporting with full details, or it's not a precedential opinion that has been widely covered.

To proceed, I need to focus on the patent at issue, US9860450. I need to:

1. Obtain the abstract and a one-line technical sketch for patent 9860450.
2. Determine the current assignee/owner of patent 9860450.
3. Search for any litigation (district court cases or PTAB IPRs) involving patent 9860450. This is the most likely way to identify the parties who would be involved in an appeal concerning this patent.

I will use USPTO and specialized patent litigation tracking sites like Unified Patents and RPX for this.

Revised Plan:

1. Patent Details: Search for "US9860450B2 abstract", "US9860450B2 claims", "US9860450B2 assignee" to get the technical summary and current owner.
2. Litigation Search by Patent: Search "US9860450B2 litigation", "US9860450B2 IPR", "US9860450B2 lawsuit" to find any associated court cases or PTAB challenges. This should identify the parties and possibly the district court case number, which could then be cross-referenced with the CAFC case number if an appeal exists.

If I cannot find specific litigation tying to CAFC 26-1485, I will indicate that the specific details of this particular CAFC appeal, beyond the patent number, are not readily available in public records as of today's date.The previous searches for CAFC case 26-1485 have not directly identified the parties or the originating district court. The search results have largely pointed to general information about the Federal Circuit or other recent decisions. This suggests the case might be very new or not yet widely reported.

I need to pivot and focus on the patent itself, US9860450B2, to uncover its owner and any associated litigation, which is the most likely path to identify the parties in the CAFC appeal.

Refined Plan:

1. Patent Details (US9860450B2): Find the abstract and technical description, and the current assignee/owner. I will use USPTO databases for this.
2. Litigation Search for US9860450B2: Search for district court cases or PTAB IPRs involving this specific patent. This should identify potential plaintiffs/patentees and defendants/petitioners, and the lower court case number if an appeal exists. I will use a combination of general web search and targeted searches on legal news sites that track patent litigation.
3. Connect to CAFC 26-1485: If a relevant district court case or PTAB proceeding is found, I will then attempt to link it to the CAFC case 26-1485.

Given the "Critical" status and the 2026 CAFC case number, it's highly probable that this is a very recent appeal. If the information is not publicly available after these targeted searches, I will state that.

Let's execute the refined plan.Despite extensive searching, specific details regarding the parties and the underlying district court case for Untitled case, CAFC Case No. 26-1485, remain publicly elusive as of today, May 29, 2026. This suggests the case is either very recently filed and has not yet been widely reported, or it does not involve a precedential opinion that would draw immediate media attention. Without direct access to PACER, pinpointing the exact parties, the accused product, or the originating district court and judge has not been possible through public web searches.

However, the patent at issue is US9860450B2. A review of general patent information indicates that US Patent No. 9,860,450 is titled "Wearable device for noninvasively measuring a physiological parameter of a user". This patent broadly covers wearable technology designed to measure physiological parameters. While the current assignee of this patent could not be definitively determined through public search results without direct access to patent assignment databases, the general technical area points towards consumer electronics and health monitoring devices.

The absence of readily available information on the parties and the accused technology makes it challenging to describe the case's notability or potential industry impact at this time. The "Critical" status suggests an expedited review or a significant issue to the parties involved, but without further public details, the specific reasons for this status are unknown. It is also unclear whether this appeal stems from a district court litigation or an administrative proceeding, such as an Inter Partes Review (IPR) at the Patent Trial and Appeal Board (PTAB).

Despite aggressive web searches against publicly available legal databases and news sources such as the Federal Circuit's opinions, USPTO PTAB records, Law360, Reuters Legal, IPWatchdog, and Patently-O, specific information detailing the key legal developments and outcome for Federal Circuit case 26-1485 associated with patent 9,860,450 is not available.

The Federal Circuit case number 26-1485 indicates a filing in 2026. Given the current date of May 29, 2026, it is plausible that detailed public records, such as docket entries, rulings, and news coverage, for such a recently filed case, especially linking it definitively to a specific patent like 9,860,450, have not yet been widely disseminated or indexed in the accessible public domain. While general Federal Circuit activity and recent decisions from 2026 are widely reported on various topics including patent eligibility, standing, and inventorship, none of these reports explicitly mention case 26-1485 or patent 9,860,450.

Furthermore, searches for parallel PTAB IPR/PGR proceedings specifically concerning U.S. Patent No. 9,860,450 did not yield any results. The USPTO's Patent Trial and Appeal Board (PTAB) databases and related news articles discuss the functions and types of proceedings (e.g., IPR, PGR), but no specific proceeding for patent 9,860,450 was identified in the search results.

Without access to the specific docket for Federal Circuit case 26-1485 or more detailed, indexed public records linking this case to patent 9,860,450, a chronological account of its legal developments, including filings, motions, claim construction, trial events, verdict, and final disposition, cannot be provided.

I am unable to identify the counsel of record representing the plaintiff(s) in Federal Circuit case 26-1485. Despite multiple attempts using web searches against various legal databases and court dockets, the specific parties (plaintiff and defendant/appellant and appellee) for this case number have not been identified. Without knowing the plaintiff in the case, it is not possible to determine their legal representation. The provided patent number, 9860450, was also not directly linked to this specific Federal Circuit case in the search results.

I am unable to identify the counsel of record representing the defendant(s) in Federal Circuit case 26-1485.

Despite aggressive web searching using the case number, court, and patent number (9860450), the specific case caption and parties for CAFC case 26-1485, particularly in the context of a patent infringement appeal, are not readily available through publicly accessible search engines as of today's date, 2026-05-29. Search results either yielded unrelated cases with similar numerical designations in different court systems (e.g., state court debt collection, real estate listings, USCIS forms) or general information about the Federal Circuit and PACER.

Access to detailed docket information, including the official case caption, parties involved, and appearances of counsel, typically requires a subscription to PACER (Public Access to Court Electronic Records) or a direct inquiry to the Federal Circuit Clerk's Office. Since direct PACER access is not available through this tool, and public aggregators have not indexed this specific, recent case number with its relevant details, I cannot provide the requested information. Therefore, it is explicitly stated that filings for this specific case are not publicly accessible through general web search, and counsel cannot be identified.
