Patent disputes over nonwovens, technical fabrics, coatings, fibers and polymer compositions require an expert who understands both the technology and how claims are construed. We provide patent litigation expert services for textile and polymer technologies.
With a research background spanning decades of textile innovation, Dr. Parachuru can speak to what a person of ordinary skill in the art knew at a given time, and whether an accused product actually practices the claims.
Common problems we're called in to solve
- Counsel needs to know if an accused fabric or fiber truly meets each claim limitation.
- A patent's validity is challenged on obviousness or prior art grounds.
- Claim terms such as 'denier', 'basis weight' or 'bicomponent' are disputed.
- An inter partes review petition needs technical declarations.
Our approach
- 1Claim-by-claim technical analysis, supported by testing of accused products.
- 2Prior art searches and assessment of the state of the art at the priority date.
- 3Declarations for claim construction, IPR proceedings and expert reports.
- 4Clear tutorials for judges on the underlying technology.
Outcomes and benefits
- Infringement and validity positions backed by measurable evidence.
- Technically accurate claim construction arguments.
- Credible testimony in district court and before the PTAB.

Frequently asked questions
Do you analyze both utility and design patents?
Our focus is utility patents covering materials, structures and processes, but we can comment on functional aspects relevant to design patent disputes.
Can you test competitor products for infringement?
Yes. We arrange appropriate fiber, structural and chemical testing to determine whether claim limitations are met.
Have you worked on patent prosecution as well?
Our litigation work is complemented by R&D consulting, which helps us understand how inventions develop in practice.
