The Tinder Patent and Why ViSi Does Not Infringe

Every dating app founder eventually gets asked the same question: doesn't Tinder own the patent on mutual matching? Won't they sue if you ship a dating app?

The short answer is no. Match Group owns multiple patents covering specific implementations of swipe-based mutual matching, but those patents do not cover the architectural category of "dating apps where both people have to agree to interact." ViSi, the engine that powers Love On Deck, is structurally different from anything covered by the Tinder patents. This article explains why, in plain English, without legal jargon.

This is not legal advice. On Deck Society has its own legal counsel (DLA Piper Phoenix). The provisional patent for ViSi was filed in late 2025, with non-provisional conversion scheduled for August 2026. The argument below is the publicly defensible version of the IP position.

What Tinder's patent actually covers

The patent most commonly cited as "the Tinder patent" is US Patent 9,733,811, granted to Tinder in 2017. It covers the swipe-based matching interface and the mutual-match unlock mechanic.

In plain English, the patent describes:

1. A system displaying profiles to a user one at a time
2. The user expressing a binary preference (positive or negative) on each displayed profile
3. Storing those preferences
4. Detecting when two users have both expressed positive preferences for each other
5. Unlocking a communication channel between the two users when mutual positive preference is detected

That is the architectural pattern. Display, decide, store, detect mutual, unlock.

The patent has been the subject of several legal challenges. Bumble and Tinder settled their patent dispute in 2020 after Bumble countersued. The patent has held up in court but is narrowly construed. It covers the specific swipe-and-mutual-match implementation, not the broader concept of "any dating app where both people have to agree."

What ViSi does instead

ViSi is the engine behind Love On Deck. It does not work like Tinder.

The architectural pattern is:

1. Each user sets Vilters (visibility filters) controlling who can see them
2. Each user sets Silters (search filters) controlling who they see during active search
3. The platform performs a deterministic bidirectional Vilter check for every potential pair of users
4. Only pairs where both users pass each other's Vilters become mutually visible
5. When a user actively searches, their Silters narrow the mutually-visible pool to their search criteria
6. Once visible, messaging is immediately available

The key difference: in the Tinder model, profiles are displayed and then preferences are expressed. In the ViSi model, preferences are expressed and then profiles are displayed. The order is inverted.

Why this matters for non-infringement

The Tinder patent specifies a system where the user is presented with profiles and then expresses preferences on those profiles. The patent claim language requires display to precede preference expression.

ViSi does not work this way. Vilters and Silters are configured before any profile is displayed. The filter check happens upstream of display. By the time you see a profile on Love On Deck, the bidirectional consent has already been computed; you are not being asked to express a preference on the displayed profile because the system has already determined that you and that user have mutually opted into being visible to each other.

This is the structural distinction that matters legally. The Tinder patent claims a process where:

• profiles are displayed → preferences are expressed → mutual match is detected → messaging unlocks

ViSi runs a process where:

• preferences are pre-configured → filters intersect → only intersected pairs are displayed → messaging is immediately available

These are different processes. They produce different user experiences. They have different technical implementations. The Tinder patent does not cover the ViSi pattern because the ViSi pattern does not follow the claim language of the Tinder patent.

The "but they both involve mutual agreement" objection

The common objection to this argument is that both systems involve mutual agreement, so they are functionally similar. A patent attorney would point out that "functionally similar" is not the legal standard for infringement. The standard is whether the accused product practices each element of at least one claim of the patent.

ViSi does not practice the display-then-preference element of the Tinder patent. Display happens after preference, not before. This is not a minor difference. It is the core architectural distinction.

The analogy that helps here: a vending machine and a restaurant both involve mutual agreement (you pay, you receive food). They are not patent-equivalent because the order of operations and the mechanism of fulfillment are different. The fact that both end in you eating food does not make a vending machine patent applicable to a restaurant.

What the patent landscape actually looks like

There are dating-app patents covering specific implementations:

• US 9,733,811 (Tinder) - swipe-based mutual matching
• US 10,664,148 (Bumble) - women-message-first mutual matching
• Multiple Match Group patents on profile-recommendation algorithms

There are no patents covering:

• Bidirectional pre-display filtering as an architectural pattern
• Visibility filters as a user-controllable feature
• Deterministic filter intersection as a matching mechanism

ViSi operates in the unpatented territory of pre-display bidirectional consent. The provisional patent filing in late 2025 was the first attempt to specifically patent this architectural pattern. The non-provisional conversion in August 2026 will determine the eventual scope.

The Bumble countersuit and what it established

Worth noting because it is the most-cited dating-app patent case: Bumble and Tinder settled their patent disputes in 2020. Bumble had countersued Tinder for infringing on Bumble's specific implementations, and the cross-claims ultimately resolved in a settlement.

The case did not establish that "any dating app with mutual matching infringes the Tinder patent." It established that Bumble's specific implementation was sufficiently similar to Tinder's that there was a genuine dispute, which is what produced the settlement.

ViSi is much further from Tinder's implementation than Bumble was. The architectural inversion (preference before display, not display before preference) is a clear technical distinction. There is no analog in the dating-app patent landscape.

Why this argument is publicly defensible

A few reasons why the non-infringement position can be argued publicly without legal exposure.

First, the position is structurally argued rather than disparaging Tinder's IP. The argument is "our product implements a different architecture," not "Tinder's patent is invalid." Different is the legal standard.

Second, the prior art on bidirectional pre-display filtering predates the Tinder patent. Operation Match in 1965 was a form of pre-display matching (the algorithm decided who matched, but the user's stated preferences gated who appeared on the match list). Various academic dating-research systems in the 1990s and 2000s used variations of pre-display preference matching. ViSi's specific implementation is novel, but the architectural category is established prior art.

Third, the public discussion is about category creation, not patent challenge. We are not claiming Tinder's patent is invalid. We are claiming ViSi is a different category. That is a marketing position, not a legal position, and it is consistent with how patent attorneys advise clients to discuss their IP relative to competitors.

The bigger picture

The dating-app IP landscape is narrower than people think. The patents that exist cover specific implementations of swipe-based mutual matching. They do not cover the entire idea of "online dating where two people have to agree."

This is good for the category. It means new architectural approaches are possible without infringing on existing IP. Consent-based dating, demographic-gated dating, intent-specific dating, and other emerging categories are all viable architectural innovations that do not run into the Tinder patent.

The reason these new categories have not emerged more aggressively is not patent risk. It is business-model risk. The existing dating apps cannot ship them without cannibalizing their revenue. New entrants like On Deck Society can.
