Claim Construction Chart

Overview

CaseMark's Claim Construction Chart skill automates the drafting of joint claim construction charts for Markman hearings in US federal patent litigation. It organizes disputed claim terms, competing party constructions, and supporting evidence into court-ready documents formatted to comply with local patent rules.

Drafting joint claim construction charts is one of the most tedious and error-prone tasks in patent litigation. Attorneys spend hours manually organizing disputed terms, cross-referencing claim language across multiple patents, formatting competing constructions side-by-side, and ensuring every evidence citation is accurate and properly formatted to local rules.

CaseMark automates the entire claim construction chart workflow. Upload your patent documents and party constructions, and the AI generates a structured, court-ready chart with properly cited evidence, agreement classifications, and formatting that complies with your district's local patent rules—freeing your team to focus on substantive claim construction arguments.

How it works

  1. 1. Upload your patent documents, prosecution history, and both parties' proposed constructions

  2. 2. AI analyzes claim language, identifies disputed terms, and maps evidence to each construction

  3. 3. Review and customize the generated chart, adjust agreement classifications, and verify citations

  4. 4. Export the finalized joint claim construction chart in your preferred format (DOCX, PDF)

Questions

What documents do I need to generate a claim construction chart?

You'll need the asserted patent(s) including full claim text and specification, the prosecution history, and both parties' proposed constructions with supporting evidence. CaseMark uses these to build a comprehensive chart with properly cited evidence for each disputed term.

Does CaseMark support local patent rules for different districts?

Yes. CaseMark supports formatting requirements for major patent venues including the Northern District of California, Eastern District of Texas, and District of Delaware. The AI adapts the chart structure, document title, and certification blocks to match your district's local patent rules.

Can the chart handle multiple patents and dozens of disputed terms?

Absolutely. CaseMark can process multiple asserted patents and organize any number of disputed terms into a structured table. Each term is tracked with its claim numbers, surrounding context, and both parties' constructions with full evidence citations.

How does CaseMark handle intrinsic vs. extrinsic evidence citations?

CaseMark organizes evidence citations by type, properly formatting specification references (column:line for utility patents, paragraph numbers for applications), claim cross-references, and prosecution history citations. Extrinsic evidence such as dictionaries and expert testimony is cited separately.

Can I edit the chart after it's generated?

Yes. CaseMark generates a fully editable document that you can review, modify, and refine. You can adjust proposed constructions, add or remove disputed terms, update agreement classifications, and customize formatting before filing.

Is this suitable for joint prehearing statements as well?

Yes. CaseMark can generate both standalone joint claim construction charts and combined joint claim construction and prehearing statements. The output adapts to your court's requirements for Markman hearing submissions.
