PATENT LITIGATION SERVICES COVER A WIDE RANGE OF SERVICES:

Pre-litigation assessment is expensive and involves a great deal of thought before framing an informed patent litigation strategy. One has to foresee the business risks, and accordingly prepare for the legal engagements. Drawing upon the extensive experience of our professional engineers, we provide litigation strategy supported by a coherent action plan. The assessment report includes:

    • Claim construction charts that account for prosecution history, intrinsic and extrinsic evidence (s), and past litigation history
    • Patent proofreading report so that any critical errors can be eliminated
    • Infringement analysis along with preliminary claim charts
    • Validity search and analysis for strength assessment and risk mitigation
    • Conduct market research and business feasibility study
    • Insights into litigation history of the party being sued

The pre-filing infringement analysis involves legal and technical processes. The legal analysis is claim construction while the technical part is a comparison of the alleged infringing products/services with construed claims. We assist various US law firms in pre-filing investigations required before filing a patent infringement lawsuit.

The US International Trade Commission (ITC) is an independent, quasi-judicial federal agency that administers certain US trade laws which provide US industries with a means to prevent unfair competition from imported goods, including Section 337 violations.

To prove a violation of Section 337, the complaining party must establish:

      • Unfair competition or an unfair act, for instance, patent infringement, etc.
      • Importation, sale for importation, or sale after importation into the United States of accused products
      • Existence of a domestic industry relating to the products or IP in question. Section 337 investigations are complex and require a unique blend of litigation, administrative law, patent laws, and technical skills

We develop claim construction charts including intrinsic and extrinsic evidence(s). We also prepare infringement charts which involve mapping of the claimed elements with the product features from available documentation in the public domain as well as physical testing/code analysis.

We help law firms in drafting and reviewing infringement contentions. A disclosure including claim chart is required by the local court at the time of claiming patent infringement. Therefore, we provide claim charts which help in identifying each element of the asserted claim within each of the accused instrumentality. We work closely with you to develop infringement contentions supported by detailed technical analysis to support your law suit.

We also help you to ascertain each limitation of the asserted claim that is alleged to be literally present or present under the doctrine of equivalents in the accused instrumentality. We review infringement and invalidity contentions to carve out the technical differences that form the basis for strong legal arguments and rebuttals. These technical differences also form the basis for non-infringement theories.

An invalidity search or prior art search involves conducting a thorough search in the patent and non-patent literature and identify references or elements that might invalidate the patent claim(s) in contention.

We have access to leading commercial patent and non-patent literature. We are well versed with various search methodologies such as IPC/CPC/US/F-term class based searching, keyword based searching, key inventor and assignee analysis, citation analysis, semantic search, etc. We also conduct literature searches in IEEE and other industry standards, trade journals, PhD thesis and dissertations, news archives, etc. The prior art search report includes details of potential prior art literature along with bibliographic details. We also analyze legal aspects and issues which may render a patent invalid. Some of these issues are related to improper antecedent basis in claims, claim enablement issues, non-compliance to duty of disclosure, incorrect entity status for renewal fees payments, etc.We conduct searches in such native languages as Chinese, Japanese, and Korean. Our teams of technical experts help you to translate patents and deliver quality reports. The invalidity search or prior art search report form a part of your invalidity contentions or assertions.
