K2K Law · New York

Patent litigation counsel for defense and enforcement.

K2K Law represents companies and patent owners in U.S. patent infringement disputes. Our New York partners bring technical analysis and courtroom experience to matters involving technology, pharmaceuticals, and life sciences.

Your starting point

One dispute.
Different business priorities.

Defending an infringement claim

An accusation can affect a product, a customer relationship, or an operating budget. We assess the asserted claims, accused technology, procedural posture, and available defenses alongside the business’s priorities. The initial work identifies what needs investigation and how to coordinate with your existing legal team.

Considering patent enforcement

For a patent owner, a credible enforcement strategy starts with evidence. We examine ownership, claim scope, potential infringement, and litigation exposure before recommending a course. The objective may be a negotiated license, a focused dispute, or further diligence before a campaign proceeds.

Building the case

Connect the claims, the technology, and the objective.

The work depends on the dispute. A useful early assessment sets priorities for the next stage rather than assuming every matter follows the same path.

  1. Assess the starting position

    Review public patent and case materials, the parties’ positions, the relevant products, and the business constraints. Identify urgent procedural questions for counsel and the evidence still needed.

  2. Develop the technical record

    Investigate claim construction, infringement, validity, and enforceability. Plan the factual and expert work needed to support the selected positions.

  3. Coordinate the forums

    Align district court strategy with related Patent Trial and Appeal Board proceedings where relevant. Consistent evidence and positions matter across the dispute.

  4. Reassess at each stage

    Use discovery, expert analysis, motions, and negotiations to reassess the options. Prepare for trial and appeal when the matter calls for them.

Your counsel

Work directly with the partners.

Gaston Kroub brings a focus on pharmaceutical and life-sciences litigation alongside a broad technology practice. Sergey Kolmykov focuses on high-technology disputes, including software and telecommunications patents.

Before we speak

Prepare a useful first inquiry.

What should I share?

Identify yourself, your organization, and the general nature of the dispute. Public patent or case identifiers can help with an initial discussion. Please leave confidential documents and time-sensitive instructions out of the web form.

Does the firm handle both sides of a dispute?

K2K’s practice includes patent infringement defense and enforcement. Representation depends on conflicts review, fit, and an agreed engagement.

Can diligence come first?

Yes. Owners considering enforcement can begin by discussing a patent portfolio diligence engagement to identify assets and questions that warrant closer investigation.
