Focused embedded circuit analysis
We conducted targeted research into cable- and connector-level identification circuitry within charging ecosystems, distinguishing general USB disclosures from structurally relevant prior art.
Inter partes review support for high-stakes power delivery technologies
Supporting a global technology leader in a complex dispute over USB charging and power delivery systems, we delivered targeted invalidity search and prior art analysis that strengthened litigation defense and post-grant proceedings strategy.
The Challenge
Patent infringement dispute in USB charging systems
A leading global technology company faced a high-stakes patent infringement dispute involving advanced power delivery and charging technologies used in consumer electronic devices. The asserted patent focused on a multi-component charging architecture, including a narrowly defined requirement: identification circuitry embedded within a cable or connector.
While prior art in USB charging systems was extensive, the key challenge was isolating disclosures that specifically addressed embedded identification mechanisms at the cable or connector level. This technical specificity significantly reduced the available prior art pool and required deep, highly targeted analysis across global technical literature.
The Solution
Structured, multi-stage patent invalidity search strategy
We executed a systematic invalidity search designed to surface highly relevant prior art under tight claim constraints, supporting both district court litigation and a planned Inter Partes Review (IPR) filing.
Our approach combined technical depth with iterative claim alignment:
Our Impact
Strengthening invalidity position in parallel proceedings
Looking to strengthen your invalidity position in complex patent litigation or IPR proceedings?
The challenge
A narrowly defined charging patent required locating prior art with embedded cable or connector identification circuitry across global USB technologies.
Why it worked
Comprehensive review and technical prior art mapping
A structured, iterative search approach aligned technical disclosures directly to tightly construed claim limitations.
The outcome
- Key prior art identified under tight constraints
- Strengthened district court invalidity position
- Supported favorable appellate outcome
