EXPRESS MOBILE, INC. v. eBay Inc.

This patent infringement suit was part of a large-scale litigation campaign by patent-holding company Express Mobile, Inc. against numerous major technology firms. The plaintiff, Express Mobile, was founded by inventor Steven H. Rempell and holds foundational patents related to website development. While it once had business operations, the company pivoted to licensing and enforcement after its founder's accident, fitting the profile of a non-practicing entity (NPE). The defendant, eBay Inc., is a global operating company that runs a well-known e-commerce marketplace connecting buyers and sellers. The lawsuit accused eBay's online marketplace platform—specifically its website and mobile applications—of infringing Express Mobile's patent. The single patent asserted in this case, U.S. Patent No. 6,546,397, is titled "Browser based web site generation tool and run time engine" and generally covers a method for building a website directly within a web browser using a "What You See Is What You Get" (WYSIWYG) interface.

The case was filed in the U.S. District Court for the District of Delaware, a procedural choice that highlights the venue's significance in patent law. The Delaware district court is consistently one of the busiest and most popular venues for patent litigation in the United States, known for its experienced judiciary in handling complex intellectual property disputes. This case is notable primarily as one of more than a dozen similar lawsuits filed by Express Mobile around the same time against companies like Google, Facebook, Microsoft, and Shopify. The broader campaign has seen mixed but significant outcomes, including a $170 million jury verdict against GoDaddy and a separate $40 million verdict against Shopify (which was later overturned), involving the same family of patents. Numerous defendants in the campaign also challenged the validity of Express Mobile's patents at the Patent Trial and Appeal Board (PTAB) through Inter Partes Review (IPR) proceedings. However, the specific action against eBay was dismissed just weeks after it was filed, suggesting an early resolution while the larger campaign against other tech giants continued for several years.

Swift End to Litigation Marks eBay's Early Exit from Broader Patent Campaign

The patent infringement lawsuit brought by Express Mobile, Inc. against eBay Inc. concluded exceptionally quickly, with the case being dismissed just over three weeks after it was filed. This rapid resolution stands in stark contrast to the multi-year legal battles Express Mobile waged against other technology companies over the same family of patents.

Key Legal Developments and Outcome:

• Filing of the Complaint (2018-08-01): Express Mobile, Inc. filed a patent infringement complaint against eBay Inc. in the U.S. District Court for the District of Delaware. The suit alleged that eBay's website and mobile applications infringed on U.S. Patent No. 6,546,397, which relates to a "Browser based web site generation tool and run time engine." This case was one of many similar suits filed by Express Mobile against major tech companies.

• Voluntary Dismissal (2018-08-24): A stipulation of voluntary dismissal was filed, formally ending the case. The dismissal was with prejudice, meaning Express Mobile cannot refile the same claim against eBay. The parties agreed to bear their own attorneys' fees and costs. The swiftness of the dismissal, just 23 days after the initial filing and before eBay had even filed an answer or any substantive motions, strongly suggests an early, out-of-court settlement, though the terms were not publicly disclosed. A USPTO filing in a related case confirms the termination date.

The case did not progress to any significant litigation milestones such as an answer from the defendant, claim construction (Markman hearing), or discovery. Its entire docket history consists of the complaint and the notice of dismissal.

Parallel PTAB Proceedings:

While eBay itself does not appear to have filed for Inter Partes Review (IPR) against the 6,546,397 patent, other defendants in Express Mobile's broader litigation campaign did. Notably, Google LLC and Facebook, Inc. filed IPR petitions against the '397 patent at the Patent Trial and Appeal Board (PTAB).

• IPR by Google (IPR2021-00700): Filed on March 31, 2021.
• IPR by Facebook (IPR2021-01224): Filed on August 10, 2021, which was instituted by the PTAB on January 14, 2022, for claim 1 of the patent.

These PTAB challenges occurred long after the eBay case was dismissed and therefore had no direct impact on its outcome. However, the broader campaign saw significant developments, including a Federal Circuit appeal in the case against GoDaddy which involved claim construction of terms in the '397 patent family. The existence of these parallel proceedings highlights the common strategy of challenging patent validity at the PTAB while district court litigation is pending, though eBay's case concluded before such a strategy would have been necessary.

Plaintiff's Counsel: Express Mobile, Inc.

The legal team representing Express Mobile, Inc. in its suit against eBay comprised seasoned patent litigators from both a national intellectual property firm and a Delaware-based firm serving as local counsel. The complaint was the primary document filed before the case's swift dismissal.

• Brian E. Farnan (Local Counsel)

  • Firm: Farnan LLP (Wilmington, DE)
  • Note: Brian Farnan is a prominent Delaware litigator and the son of former District of Delaware Judge Joseph J. Farnan, Jr.; he frequently serves as local counsel in major patent cases within the district.

• Michael W. Shore (Lead Counsel)

  • Firm: The Shore Firm (Dallas, TX) (Note: At the time of the filing, he was with Shore Chan DePumpo LLP).
  • Note: Shore has a long history of representing plaintiffs in high-stakes patent litigation, including securing a notable $17.5 million verdict for VirnetX against Microsoft in 2010.

• Alfonso Chan (Lead Counsel)

  • Firm: Shore Chan LLP (Dallas, TX) (Note: Formerly Shore Chan DePumpo LLP).
  • Note: Chan has been a key attorney alongside Michael Shore in many of Express Mobile's successful litigation campaigns, including the significant verdicts against GoDaddy and Shopify.

• Christopher H. Day (Of Counsel)

  • Firm: The Shore Firm (Dallas, TX) (Note: Formerly Shore Chan DePumpo LLP).
  • Note: Day has extensive experience in patent law, including prior roles as a patent examiner and in-house counsel, and has been involved in numerous actions with the firm.

This counsel information is sourced directly from the civil docket for the case, specifically the original complaint filed on August 1, 2018. The attorneys from the Texas-based Shore Chan DePumpo LLP (now known as Shore Chan and The Shore Firm respectively) led the litigation strategy, while Brian Farnan of Farnan LLP fulfilled the procedural requirement for Delaware local counsel.

Defendant eBay's Counsel Not on Record Due to Swift Dismissal

Due to the exceptionally rapid termination of the lawsuit, no counsel for the defendant, eBay Inc., ever filed a notice of appearance on the public docket. The case was voluntarily dismissed by Express Mobile just 23 days after the complaint was filed, precluding the need for eBay to formally answer the complaint or otherwise appear through counsel.

While no attorneys are officially listed on the docket for eBay, in similar patent infringement cases brought by Express Mobile, eBay has been represented by attorneys from the firms Paul Hastings LLP and Morris, Nichols, Arsht & Tunnell LLP. It is plausible that counsel from these firms were retained to negotiate the swift resolution that led to the dismissal, even without making a formal appearance in court.

For context, key attorneys who have represented eBay in other patent matters include:

• Stephen B. Kinnaird

  • Firm: Paul Hastings LLP (Washington, D.C.)
  • Note: Kinnaird is a veteran appellate and intellectual property litigator who has represented major tech companies in high-stakes patent disputes.

• Jack B. Blumenfeld

  • Firm: Morris, Nichols, Arsht & Tunnell LLP (Wilmington, DE)
  • Note: A highly-regarded "dean of the Delaware IP bar," Blumenfeld frequently serves as Delaware counsel for major corporations in patent litigation.

However, to reiterate, neither these attorneys nor any others formally appeared on the record for eBay in Express Mobile, Inc. v. eBay Inc., 1:18-cv-01166, as the case was dismissed before any responsive pleadings were due.
