A patent about coffee-shop routers now points at a brokerage account
On 3 September 2026, Reframe Technologies LLC sued Robinhood Markets, Inc. in the District of Delaware, asserting U.S. Patent No. 7,552,870, "Trading network resources." The patent describes a 2006 system for letting WiFi router owners barter spare bandwidth for roaming internet access. Its mechanism is a settlement engine, and that is what makes it reach a long way from WiFi. Case 1:26-cv-01113 (D. Del.). Docket, USPTO record and public litigation datasets reviewed 14 September 2026. The complaint itself is available through PACER and was not reviewed for this article.
Settlement, not access
By 2006 the individual building blocks were established. Gateway authorisation worked. Prepaid and post-paid billing for network usage worked. Roaming agreements between independently operated networks worked. What remained unsolved was settlement without a matching engine or an external payment.
The patent's own background section makes the scale of the gap explicit. More than ten million internet-connected wireless access points had been deployed worldwide, almost all of them locked. The largest international hotspot operators of the day, among them Boingo, T-Mobile, Wayport and iPass, covered roughly twenty thousand access points between them. Every new gateway required a negotiated billing relationship, so coverage grew slowly and charges stayed high.
The proposal was to let the other 9.98 million join in. Open your router, earn credit for the bandwidth strangers consume, spend that credit on somebody else's router when you travel. No subscription, no voucher, no card at the point of use.
The mechanism has three parts. An Earned Balance distinguishes credit earned by providing access from money paid in as a Cash Balance, with each device configured to spend earned credit First, Last or Never. A direct authorise-or-deny protocol answers yes or no for one specific gateway and one specific device, rather than pooling supply and demand. And a credit reservation holds the maximum possible charge at authorisation, then reconciles the actual amount at session end and releases the remainder.
The invention is not in the radio. It is in how the transaction settles.
What the applicant distinguished himself from
The specification names its closest prior art directly, which makes this the least arguable part of the record. Two references are identified as telecommunications trading systems: ANIP's U.S. 6,005,926, a method for trading telecommunications services, and Arbinet's U.S. 6,731,729, a method for settling trading accounts, which also provided for credit earned by supplying network resources to be traded for usage. A third, U.S. 6,526,390, covered independent billing settlement for roaming wireless subscribers using a credit card.
The applicant's stated point of difference is narrow and specific. Those systems match a suitable buyer to a suitable seller from a pool of participants. His does not match anybody. It returns an explicit authorisation or denial for one named pair.
The wider field was moving in parallel on adjacent pieces. Gateway-level access control and authentication addressed gatekeeping but not payment. Roaming and inter-operator handoff addressed continuity of connection but not settlement. Prepaid-balance and data-service billing addressed charging mechanics while still assuming a conventional payment relationship. Single-sign-on and cross-operator credentialing addressed identity but not credit exchange.
Each track had a piece. The subject invention combined gatekeeping, charging and credit trading into one mechanism, and replaced the matching engine with a direct exchange between two named parties.
Sixteen quiet years, then nineteen busy months
International family members were filed through the PCT in 2007 and pursued in China, Japan and Europe. Then nothing observable for sixteen years. No assignee company, no litigation.
Robinhood is one of at least sixteen defendants. The docket numbers tell part of it: 1:26-cv-01112 is Roblox Corporation, 1:26-cv-01113 is Robinhood, 1:26-cv-01114 is Psyonix LLC, the studio behind Rocket League. Three consecutive numbers, all filed on 3 September 2026.
| Court | Cases recorded | Period |
|---|---|---|
| District of Delaware | 9 | 2025 – 2026 |
| Western District of Texas | 4 | 2025 |
| Eastern District of Texas | 2 | 2025 |
| Southern District of New York | 1 | 2025 |
Defendants identified in the public record include Robinhood Markets, Roblox Corporation, Psyonix LLC, Lucid Group and Odacite. A brokerage, two game companies, an electric vehicle manufacturer and a skincare brand. Reframe Technologies LLC filed a Rule 7.1 disclosure in this case stating no parent corporations or affiliates.
Why a router patent arrives at a trading app
Nothing connects a brokerage, a game studio and a cosmetics company at the level of WiFi. If there is a connection it sits at the level of the settlement mechanism, and the patent's own classifications point that way. Alongside the expected networking code for data communication billing, it carries G06Q20/10 for electronic funds transfer architectures and G06Q40/04, which the classification scheme defines as "Trading; Exchange, e.g. stocks, commodities, derivatives or currency exchange."
Strip the hotspot framing and the specification describes an account with two kinds of balance, a rule for which is consumed first, a reservation placed against a pending transaction, an authorise-or-deny response, and a reconciliation that releases what was not used. Several Robinhood mechanisms sit close to that shape.
| What the patent describes | Structurally comparable mechanism |
|---|---|
| Credit reserved at authorisation, reconciled at session end | Instant and Gold buying power extends spendable power against pending deposits or unsettled sale proceeds, then reconciles once settlement completes. |
| Earned Balance held separately from Cash Balance | Cash balances, including yield-bearing cash, held separately from invested holdings. Robinhood's balances are not earned by resource-sharing between independent operators. |
| Authorise-or-deny decision against available credit | Options and margin orders authorised in real time against buying power and account risk limits, with the debit or credit reconciled at trade settlement. |
| Reservation released after actual usage is known | Crypto wallet transfers checked against a wallet balance and authorised or declined instantly, with network fees reconciled after on-chain confirmation. |
Each of these is a standard brokerage or fintech account-management pattern, and the resemblance is structural rather than legal. This analysis works from the specification, the classifications and the public docket; the claim text has not been examined, and the claims are what define the monopoly. Whether any of these mechanisms falls within them will turn on how narrowly terms written for physical network access gateways are construed, and on whether two independently owned parties are trading capacity directly, which is the problem the specification says it solves, rather than one firm managing its own customers' balances.
There is a second question running the other way. If instant authorisation against a reserved balance was already established practice in prepaid telecoms billing before March 2006, and the specification itself says much of it was, then the same prior art that the applicant distinguished may bear on how much of this architecture was novel in the first place.
Common questions
Which patent is asserted against Robinhood?
U.S. Patent No. 7,552,870, "Trading network resources," identified in the court's Form AO-120 report to the Commissioner of Patents and Trademarks, filed on the docket on 3 September 2026.
What does US 7,552,870 describe?
A network resource trading exchange that lets wireless access point operators earn credit by providing internet access to others and spend that credit on access elsewhere, using an Earned Balance and Cash Balance account structure, a direct authorise-or-deny protocol, and a credit reservation reconciled at session end. The claim text has not been reviewed here.
When does the patent expire?
Its adjusted expiration date is 2 May 2027, roughly eight months after this case was filed.
Who is Reframe Technologies LLC?
The current assignee of US 7,552,870, recorded in the USPTO assignment database on 15 October 2025, sixteen years after the patent granted. In this case it filed a Rule 7.1 disclosure stating that it has no parent corporations or affiliates. The named inventor is Adrian Paul Jones, and the patent was originally recorded to an individual rather than a company.
How many cases have been filed on this patent?
Public litigation datasets record at least sixteen district court cases beginning in 2025, concentrated in the District of Delaware and the Western and Eastern Districts of Texas. Robinhood, Roblox and Psyonix were sued on the same day under consecutive case numbers.
What prior art did the applicant distinguish?
The specification names ANIP's U.S. 6,005,926 and Arbinet's U.S. 6,731,729 as telecommunications trading systems that match buyers to sellers, and U.S. 6,526,390 for card-based roaming settlement. The stated point of difference is that the invention performs no matching and instead returns an explicit authorisation or denial for one specific pair.
Does this article say Robinhood infringes the patent?
No. It describes the patent, its assignment history and the pattern of filings, and sets out structural resemblances that would need to be tested against the claims. It makes no infringement, validity or enforceability determination, and no court has ruled on any of these questions.
