Patent Infringement and Invalidity Analysis
Cyberonix conducts pre-litigation infringement and invalidity assessments for counsel and IP holders evaluating whether to assert claims, defend against an assertion, or license. The analytical methods are those the firm uses to produce trial-ready claim charts and invalidity contentions, calibrated to the decision the client is making rather than to the courtroom. The work rests on the artifacts that govern the assertion in litigation: the asserted claims and their prosecution history, accused-product documentation and source code where available, and the prior art that bears on the asserted claims. Each conclusion traces back to those artifacts.
Infringement Analysis for Assertion and Licensing
Infringement analysis turns on whether each asserted claim limitation can be located in the structure or behavior of the accused product, and the deliverable separates the limitations the public record can establish from those whose evaluation requires code-level discovery.
Each asserted claim is read against the specification and prosecution history to fix what was claimed and what was given up. Limitations are then mapped to the accused product from publicly available materials: product documentation, technical specifications, regulatory filings, standards-body disclosures, and public source repositories where the product incorporates open-source components. Where the IP holder has lawful access through an audit clause, license provision, or M&A diligence right, source code is brought into the analysis. Each limitation in the claim chart cites the artifact that supports the read.
Where literal infringement is absent on one or more limitations, the doctrine of equivalents is analyzed under the function-way-result framework, which asks whether the accused implementation performs substantially the same function in substantially the same way to achieve substantially the same result. Prosecution-history estoppel is evaluated in parallel, because amendments and arguments made during prosecution can bar reliance on equivalents for the limitations they touched. Cyberonix positions the equivalents theory in the pre-litigation deliverable, not after a literal read falters in negotiation.
The deliverable distinguishes claims whose infringement read can be established from public materials alone from claims whose strength depends on source-code-level discovery: server-side behavior, internal APIs, or proprietary algorithms not externally observable. Counsel uses that distinction to set the posture: which claims are ready to assert today, which require code-level discovery before the question can be answered, and which the licensing demand should anchor on.
Invalidity Analysis for Defense and Cross-License Posture
Invalidity analysis sets the floor of any licensing demand and the ceiling of any defensive posture, and the same record supports both sides of that calculation.
Prior-art search is conducted across patents, publications, products, and prior source-code releases, anchored to the asserted claims rather than to the patent as a whole. Anticipation under §102 requires a single reference to disclose every limitation of the claim, arranged as in the claim. Obviousness under §103 is assessed under the Graham factors (the scope and content of the prior art, the differences between the prior art and the claims, and the level of ordinary skill in the field), together with whether a skilled artisan would have had reason to combine the references with reasonable expectation of success. Secondary considerations are identified where the record supports them.
Section 112 challenges are evaluated alongside the §§102/103 analysis. Written description, enablement, and definiteness exposure is identified for claims whose breadth runs past what the specification teaches. Means-plus-function construction under §112(f) is flagged where the specification discloses only functional language without algorithmic structure, frequently dispositive for software claims. Patent eligibility under §101 is assessed under the Alice/Mayo two-step framework, with attention to whether the elements, individually and as an ordered combination, recite an inventive concept beyond well-understood and conventional computer implementation.
Where the IP holder operates in the same product market as the prospective targets, cross-license exposure is analyzed in parallel. The holder’s own products are mapped against the targets’ likely retaliatory portfolios; the analysis surfaces what the counterparty can credibly assert back and how that posture shifts the assert-versus-license calculation. For operating companies in active markets, this counter-assertion record is often the determining input into the settlement architecture.
Pre-Litigation Decision Frame
The infringement and invalidity record exists to answer one of four pre-litigation questions (assert, license, defend, or walk away), and the analysis is calibrated to which one.
Assertion requires the strongest infringement read the public record can support, paired with a clear-eyed view of invalidity exposure on the claims to be asserted. Licensing requires the same record, calibrated to the royalty rate and structure being sought rather than to maximum damages. Defense requires the inverse: the strongest invalidity record against the asserted claims, paired with the cleanest non-infringement read on the accused functionality. Walking away requires honest acknowledgment that the infringement read is too thin or that invalidity exposure overwhelms the claim’s value.
Where the public artifacts are insufficient to evaluate accused-product behavior (runtime data flows, undocumented network protocols, or implementation details the public record does not expose), source code review and reverse engineering recover the technical record that public materials cannot supply. Binary reverse engineering, network-protocol analysis, and runtime instrumentation extend the analytical reach to questions public documentation does not answer. Whether to commission that work is itself part of the pre-litigation analysis, because its cost and timeline shift the economics of the assertion.
Pre-litigation analyses are documented to the standard that would support their use as expert reports if the matter were filed today, so the record built at the assertion-decision stage is not rebuilt when the case proceeds.
Our Experts
The Cyberonix infringement and invalidity team is the same group of senior consultants who staff the firm’s litigation patent practice. Each holds a faculty appointment at a U.S. research university, with recognitions including IEEE Fellow status, ACM Distinguished Member status, and named professorships at leading research institutions. Industry experience spans the technology areas in which software-patent assertions are most actively pursued: distributed systems, machine learning, mobile and web platforms, networking, and software security. Engagements are staffed so the lead consultant’s research record aligns with the technology at issue.
