Stormborn Technologies, LLC v. Topcon Positioning Systems, Inc.

Background

Stormborn brought a patent-infringement action against Topcon, alleging that Topcon’s products infringed claims 11 through 14 of U.S. Patent RE44,199, titled “Variable Throughput Reduction Communications System and Method.” The patent concerns spread-spectrum communications systems. Topcon renewed a motion under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal when a complaint does not state a legally sufficient claim. Topcon argued that the asserted patent claims covered ineligible subject matter under 35 U.S.C. § 101.

The parties agreed that claim 11 represented independent claims 11 and 13. Claim 11 describes a receiver with demodulator, decoder, command processor, transmitting, and multiplexer circuitry. The command processor responds to the error rate of decoded channels by generating a data-rate control signal that controls the transmitter’s data rate. Claims 12 and 14 are dependent claims involving decoding forward error-correction codes at different rates.

Section 101 framework

Section 101 generally allows patents for new and useful processes, machines, manufactures, compositions of matter, and improvements, but excludes laws of nature, natural phenomena, and abstract ideas. Courts apply the two-step framework from Alice Corp. v. CLS Bank. First, the court asks whether the claims are directed to an excluded concept. If so, the court considers whether the claim’s elements, individually or in combination, contain an inventive concept—something that transforms the excluded concept into a patent-eligible application.

At the motion-to-dismiss stage, the court accepted Stormborn’s factual allegations as true and viewed the representative claim in light of the patent specification.

Court’s analysis

Topcon characterized claim 11 as the abstract idea of slowing a data stream when it becomes too difficult to process accurately. The court found that characterization too general and insufficiently tied to the claim language.

The court held that claim 11 was not merely defined by the result it sought. The claim was tied to a specific command processor in a receiver and described generating a data-rate control signal based on the error rate of decoded channels. In the court’s view, the claimed arrangement addressed interference affecting spread-spectrum systems, particularly interference involving stations near the edge of a cell.

The court also concluded that claim 11 described an improvement over prior communication systems. Earlier approaches allegedly changed the receiver’s architecture, timing, or transmitter data framing. By contrast, the claimed system controlled the transmitter’s data rate from the receiver using a closed-loop method and added a command processor to improve interference immunity.

The court separately considered whether the claim merely limited an abstract idea to a wireless technological environment. It concluded that the claim did more than identify a technological setting because it described a specific improvement to spread-spectrum communications.

Even assuming that claim 11 involved the known concept of controlling or “throttling” an information stream, the court held that the claim’s particular arrangement of components could supply an inventive concept under the second step of the Alice framework. The court further stated that factual disputes about whether aspects of the claims were well understood, routine, or conventional could prevent dismissal at the pleading stage.

Topcon also argued that the patent did not explain sufficiently how to achieve the claimed result. The court stated that this argument was more appropriately addressed in a validity challenge under 35 U.S.C. § 112, rather than in a Section 101 eligibility challenge.

Disposition

The court denied Topcon’s motion to dismiss on the ground that the ’199 Patent claims ineligible subject matter under 35 U.S.C. § 101. The opinion did not state that the court decided whether Topcon actually infringed the patent.
