Street Spirit IP v. eHarmony: Infringement Claim Dismissed With Prejudice
Street Spirit IP, LLC asserted US8850535B2 — covering identity verification methods in social networks using ratings — against eHarmony, Inc. in the Central District of California. The court granted eHarmony's motion to dismiss with prejudice and without leave to amend, ending the case just 148 days after filing.
Identity verification patent claim ends at pleading stage
On 28 March 2023, Street Spirit IP, LLC — a patent assertion entity represented by Ramey LLP — filed suit against eHarmony, Inc. in the U.S. District Court for the Central District of California (Case No. 2:23-cv-02252). The sole patent asserted was US8850535B2, directed to methods and systems for identity verification in a social network using ratings. Street Spirit IP alleged that eHarmony's platform infringed this patent.
The case closed on 23 August 2023, 148 days after filing. The recorded basis of termination is 'Dismissed with Prejudice.' The court's order, entered pursuant to eHarmony's motion to dismiss, states that the case is dismissed with prejudice and without leave to amend, and that plaintiff shall take nothing from this action. The specific grounds on which the motion to dismiss was granted are not detailed in the available record.
Resolution in under five months on a motion to dismiss — before any discovery or claim construction — is consistent with early-stage invalidity or eligibility challenges that succeed at the pleading level. The denial of leave to amend signals the court found no viable path to a compliant complaint. Whether the dismissal was based on subject-matter eligibility under 35 U.S.C. § 101, failure to state a claim, or another ground is not disclosed in the available record.

US8850535B2 — Identity verification in social networks using ratings
Any company building or operating identity verification, trust-and-safety rating, or user reputation systems within a social network or online platform context should assess exposure to US8850535B2. The patent's claims around ratings-based identity verification are broad enough to potentially read on a range of feature implementations. The eHarmony dismissal does not affect the patent's enforceability against other parties.
Official order — verbatim text
The court's order dismisses the case with prejudice and without leave to amend, directing that plaintiff shall take nothing. This phrasing reflects a dispositive ruling on eHarmony's motion to dismiss — ending the litigation in its entirety at the pleading stage. The denial of leave to amend indicates the court found no amendment could remedy the complaint's deficiencies. The specific legal ground for dismissal is not disclosed in the available docket record.
Dismissed with prejudice: what the ruling means for both parties
Motion to dismiss granted — no leave to amend
A dismissal with prejudice on a motion to dismiss ends the litigation on the merits without trial or discovery. 'Without leave to amend' means the court determined that no amended pleading could cure the deficiency. The plaintiff is permanently barred from reasserting the same claims against eHarmony under US8850535B2 in this court.
Final on the meritsStreet Spirit IP's claim extinguished at the pleading stage
Street Spirit IP obtains no relief and is barred from relitigating these infringement claims against eHarmony. The dismissal with prejudice, combined with the court's refusal to grant leave to amend, suggests the complaint was found to be fundamentally deficient. The specific terms of the dismissal are reflected in the court's order; no undisclosed settlement terms are recorded.
No damages recoveredeHarmony prevails without reaching the merits of infringement
eHarmony, represented by Baker & Hostetler LLP, successfully terminated the litigation at the pleading stage. The dismissal with prejudice provides a strong procedural barrier against Street Spirit IP reasserting these claims. eHarmony avoided discovery, claim construction proceedings, and trial exposure on this patent.
Early full victory for defendantPleading-stage dismissals raise the bar for PAE assertions in this domain
A with-prejudice dismissal on a motion to dismiss — particularly without leave to amend — signals that courts in the Central District of California are scrutinising identity verification patent complaints at the pleading level. For platforms operating in the online dating and social networking space, this outcome suggests that early motion practice can be a cost-effective defence strategy against broad software patent assertions.

Monitoring claim trends in this area helps product and IP teams anticipate where the next enforcement frontier may emerge.
Filing trend analysiseHarmony's IP position in online matching and identity systems
eHarmony's successful early defence suggests an IP team prepared to challenge assertions at the pleading stage. Examining eHarmony's own patent filings in user matching, identity authentication, and platform trust can reveal both defensive assets and potential offensive IP strategy in the online relationship platform sector.
Competitor patent watchAdjacent innovation opportunities in decentralised identity verification
Beyond traditional ratings-based models, emerging approaches to social network identity — including decentralised identity (DID), zero-knowledge proofs, and biometric trust anchors — represent areas where patent white space may exist. For R&D teams, these adjacencies offer differentiated filing opportunities outside the claim scope of US8850535B2.

What this case signals for the identity verification IP landscape
A swift dismissal with prejudice highlights growing judicial scrutiny of software-based identity verification patents at the pleading stage.
Pleading-stage dismissal is a viable and cost-efficient defence strategy
eHarmony's success on a motion to dismiss — resolved in 148 days, before any discovery — confirms that well-crafted early motion practice can neutralise patent assertion entity (PAE) claims in the C.D. Cal. Social network and online platform defendants facing similar assertions should evaluate pre-answer motion options early.
Identity verification patents face heightened scrutiny in software contexts
US8850535B2 covers methods and systems for identity verification via ratings in social networks — a technology category that courts have increasingly evaluated for patent eligibility and pleading sufficiency. The no-leave-to-amend ruling suggests the court found the asserted claim incurably deficient, a meaningful signal for others in this space.
Street v Eharmony — key questions answered
Street Spirit IP, LLC filed a patent infringement action against eHarmony, Inc. in the Central District of California on 28 March 2023, asserting US8850535B2 covering identity verification in social networks using ratings. The court granted eHarmony's motion to dismiss, and the case was dismissed with prejudice and without leave to amend on 23 August 2023, 148 days after filing.
Dismissed with prejudice means Street Spirit IP is permanently barred from reasserting the same infringement claims against eHarmony based on US8850535B2. The additional denial of leave to amend indicates the court found no version of an amended complaint could cure the deficiency. The specific legal ground — such as eligibility, failure to state a claim, or another basis — is not disclosed in the available record.
US8850535B2 (application no. US13/204582) is a U.S. patent directed to methods and systems for identity verification in a social network using ratings. It covers trust and identity infrastructure within social platforms, a technology area relevant to online dating, marketplace, and community platforms that incorporate user rating or verification features.
No. The dismissal with prejudice in this action is specific to the claims between Street Spirit IP and eHarmony. US8850535B2 itself remains in force and could be asserted against other defendants. Companies operating identity verification, trust scoring, or ratings-based features within social platforms should conduct independent FTO analysis of this patent and any related family members.
Resolution in 148 days, before discovery or claim construction, is consistent with a dispositive motion to dismiss that succeeded at the pleading stage. Such early terminations often — though not always — reflect challenges to subject-matter eligibility under 35 U.S.C. § 101 or failure to adequately plead infringement. The precise ground is not specified in the available docket data.
