Island Intellectual Property LLC v. Stonecastle Cash Management LLC

Background

Island Intellectual Property, LLC sued StoneCastle Cash Management LLC and affiliated entities, alleging patent infringement and other federal and state-law claims. The patents concerned a computer-implemented multibank reciprocal-deposit system and a computerized model for managing account balances across multiple banks and accounts. Island also alleged that StoneCastle misappropriated trade secrets relating to cash-management and money-regulation systems.

The dispute arose after StoneCastle Insured Sweep LLC, a StoneCastle subsidiary, acquired Intermedium Financial LLC, which licensed Island’s intellectual property. Island alleged that StoneCastle later used the intellectual property without obtaining additional licenses while offering federally insured cash accounts to local government entities.

Patent Claims

The court applied the two-step framework established by the Supreme Court for determining whether a patent claims an abstract idea. First, it asks whether the claims are directed to an abstract idea. If so, it asks whether the claims contain an “inventive concept”—a feature or combination of features that adds significantly more than the abstract idea itself.

For the four Reciprocal Deposit Patents, the court treated claim 1 of the ’766 Patent as representative. It held that the claims were directed to the abstract idea of using a multibank deposit program to remain within federal insurance limits. The court characterized dividing and transferring funds among banks to stay within insurance limits as a fundamental economic practice. It rejected Island’s argument that the claims improved computer operation, finding that the computer-related limitations merely instructed users to carry out the abstract idea on a computer at a high level of generality.

At the second step, the court found no inventive concept. Island did not identify a specific technological problem solved by the patents or a specific innovation over the prior art. The court therefore held that the Reciprocal Deposit claims were directed to patent-ineligible subject matter and granted the motion to dismiss as to those claims.

For the Allocation Model Patent, the court held that the representative claim was directed to the abstract idea of performing bookkeeping for a multibank, multi-account deposit system. The claimed steps included gathering account information, calculating excess capacity, allocating funds, and updating account records. The court found that these tasks could be performed manually and that placing them on a computer did not make them patent-eligible. It also found no inventive concept in the claimed process. The court granted the motion to dismiss as to the Allocation Model Patent as well.

Trade-Secret Claim

Island brought a claim under the Defend Trade Secrets Act, a federal law that allows the owner of a trade secret to sue for misappropriation. To state such a claim, a plaintiff must identify the alleged secret with enough detail to give the defendant fair notice, without necessarily revealing the secret itself.

Island described the alleged trade secrets only as “certain proprietary, secret and confidential information relating to cash management and money regulation systems” and the implementation of the patent inventions. The court held that this description was too general because it did not identify, even in broad categories, the type of information allegedly taken. The court therefore dismissed the trade-secret claim.

The court did not decide whether Island plausibly alleged that StoneCastle misappropriated the information. It also did not consider a declaration submitted with Island’s opposition because the declaration was not properly before the court on a motion to dismiss.

State-Law Claims

After dismissing all federal claims at an early stage, the court declined to exercise supplemental jurisdiction—the court’s authority to hear related state-law claims—in its discretion. It dismissed all remaining state-law claims without prejudice.

Leave to Amend and Disposition

The court granted Island leave to amend the trade-secret claim. It denied leave to amend the patent claims because amendment would be futile. The court’s conclusion states that StoneCastle’s motion to dismiss was granted, directed the Clerk to close the motion, and set June 26, 2020, as the deadline for any amended complaint. If Island did not file an amended complaint by that date, the court stated that final judgment would be entered.
