How to create a claims and defenses evidence matrix for Copyright Infringement Matters

Create a copyright claims and defenses evidence matrix by separating each asserted work, defendant, disputed act, and exclusive right, then linking each issue to supporting evidence, adverse evidence, and unresolved questions. Identify exact work versions, trace ownership and permissions, and distinguish factual comparisons from legal conclusions. The deliverable is a source-linked working table showing what counsel can presently support, which defenses require investigation, and who must resolve each material gap before the next litigation decision. Update it when new evidence changes an assessment.

When to use this workflow

Use this workflow when a demand, complaint, production, or technical comparison raises competing accounts of creation, copying, ownership, or permission. It suits outside counsel evaluating allegations and in-house teams coordinating creative, licensing, commercial, and technical records.

Center the matrix on a defined decision: narrowing allegations, assessing permission, or identifying evidence needed for a motion or examination. It should not become a document inventory, discovery tracker, or damages model.

This guide addresses US copyright law and federal litigation. Federal procedural and evidentiary rules do not automatically govern state proceedings, arbitration, or Copyright Claims Board matters. Check controlling precedent, applicable orders, contract law, and foreign-law issues separately.

What you need

Assemble an initial record with stable document IDs and retrievable locations:

• Claim definition: pleadings or demands identifying works, defendants, challenged conduct, asserted rights, and relevant periods.
• Work versions: native creative files, revision histories, published copies, registration deposits, and preserved accused material.
• Ownership records: creator identities, employment or commissioning documents, executed assignments, and work schedules.
• Permission records: licenses, amendments, approval emails, sublicensing records, and termination communications.
• Use evidence: dated captures, distribution records, access communications, source files, and relevant witness accounts.
• Registration and remedy records: certificates, application correspondence, publication evidence, infringement commencement evidence, and financial records.

Record collection limits immediately. An undated screenshot, unsigned assignment, or missing license schedule is an uncertainty, not a completed factual premise.

Use the template

The companion template is Copyright Infringement Matters — Claims and defenses matrix. Copy this table into your working document or spreadsheet. Use a parent row for each work–defendant–act–right combination and linked issue rows for ownership, permission, or another disputed question.

Use persistent IDs, such as C01, rather than changing spreadsheet coordinates. Identify versions by document ID and revision marker. Describe conduct concretely: uploading an image to a campaign page is more useful than “infringement.”

Evidence cells need a factual proposition and pinpoint citation: document ID plus page, clause, timestamp, frame, or code location. Supporting and adverse evidence are relative to the stated position, not necessarily your client.

Distinguish factual gaps from legal questions. The final field records an action, responsible person or role, and status. Keep lengthy comparisons in linked working papers.

Step by step

1. Define the claim units and decision purpose

Identify the immediate decision, then separate works, accused actors, challenged acts, asserted rights, and relevant periods. Identify whether a position is an allegation, an opposing contention, or counsel’s provisional assessment.

Section 106 enumerates exclusive rights; § 102(b) excludes ideas, procedures, systems, and similar subject matter from protection. A row therefore needs more than an assertion of resemblance. These provisions do not supply a universal substantial-similarity test: identify governing precedent for the work category. Copyright Act, §§ 102 and 106. (copyright.gov)

Record: each claim unit, the position being tested, its relevant period, and the governing-authority question. Do not merge defendants simply because they used the same asset.

2. Establish versions and comparison evidence

Preserve untouched source copies. Identify the exact claimant and accused versions, then map allegedly copied material by page, frame, timestamp, image region, or code location. Describe differences as carefully as similarities.

Separate observation from inference. A shared spelling error is observable; copying is an inference requiring further analysis. An attachment email may establish transmission without establishing that a particular recipient opened or used the file.

Flag potentially unprotected material for counsel’s analysis. Do not treat a similarity score as a legal conclusion or substitute a convenient later version for the version used during the disputed period.

Record: pinpoint comparisons, differences, access evidence, uncertain version relationships, and the linked comparison schedule.

3. Trace ownership and permission during the disputed use

Map the creator-to-claimant chain against executed instruments and schedules. Section 201 generally places initial ownership with the author, subject to provisions including works made for hire. Payment or commissioning alone does not establish that status; apply § 101’s definition. Copyright Act, § 201; § 101. (copyright.gov)

Section 204(a) generally requires a signed writing for ownership transfers other than transfers by operation of law. Ownership of a physical object is distinct from copyright ownership under § 202. Do not apply the transfer-writing requirement indiscriminately to permission: § 101 excludes nonexclusive licenses from its ownership-transfer definition. Copyright Act, §§ 202 and 204; § 101. (copyright.gov)

Compare permissions with the actual work, media, territory, term, sublicensing, amendments, and notices. Interpretation depends on the language, governing law, and facts.

Record: each chain link and clause, contrary communications, and gaps affecting the disputed period.

4. Develop defense-specific evidence questions

Give each material defense its own position and assessment. For permission, compare scope with conduct. For independent creation, seek native files, revision histories, creator accounts, and contrary access evidence; do not assume one item resolves copying.

For fair use, organize evidence around purpose and character, nature of the copyrighted work, amount and substantiality used, and effect on the potential market or value. These statutory factors are not a mechanical checklist, and statutory examples are not automatic exemptions. Copyright Act, § 107. (copyright.gov)

Ask what each source establishes about the particular use. A company description does not necessarily establish that use’s purpose. Missing licensing data does not establish absence of market effects.

Record: supporting and adverse facts, unresolved defense questions, and matter-specific authority still needed.

5. Separate registration and remedy questions

Create linked rows rather than treating registration and remedy eligibility as one merits issue. Section 411(a) generally conditions an infringement action concerning a United States work on preregistration or registration, subject to exceptions and a refusal procedure. Section 412 separately restricts statutory damages and attorney fees by reference to registration, publication, and infringement commencement. Copyright Act, §§ 411–412. (copyright.gov)

Verify dates against sources and identify the applicable statutory pathway. Distinguish application submission, registration, publication, and alleged commencement; do not treat them as interchangeable. A certificate alone does not resolve every remedy question.

Record: relevant dates and sources, disputed events, exceptions requiring assessment, and linked financial analysis without unsupported damage figures.

6. Test foundations and contradictions

Ask how each important item could be established through a witness, source system, or other foundation. Federal Evidence Rule 901(a) requires sufficient evidence that an item is what its proponent claims. Rule 602 generally requires a personal-knowledge foundation. Authentication does not independently resolve hearsay or other admissibility issues. Federal Rules of Evidence, Rules 602 and 901. (uscourts.gov)

Distinguish firsthand knowledge from information supplied by others. Compare accounts against file histories, instruments, and contemporaneous communications. Repeated citations to one document are not independent corroboration.

Record: foundation questions, contradictory passages, witness propositions, and restrictions on reliance pending verification.

7. Prioritize gaps and release a decision-ready version

Rank gaps by their effect on the immediate decision. A missing assignment schedule may matter more than hundreds of duplicative campaign emails. Choose a targeted repository search, client clarification, witness follow-up, or authority review.

Assign every material gap an owner and review milestone. Preserve the distinction between “not found in reviewed materials” and “does not exist.” When evidence changes an assessment, retain enough history to explain why.

Record: next action, owner, review milestone, status, and current recommendation. Release unresolved issues visibly rather than forcing every row into a yes-or-no conclusion.

Worked example

Fictional scenario: Larkspur Diagram Studio alleges that Northglass Learning reproduced three illustrations in a paid training package during April–June 2026. Counsel must decide which allegations to maintain. All parties, documents, dates, and clause descriptions here are fictional.

The reviewed set contains editable artwork, an assignment referencing an absent schedule, an internal-training license, a pilot approval email, and two package versions: an approved pilot and a later paid edition. A comparison schedule identifies a shared arrangement and typo in illustration A. Illustration C appears beside commentary. The reviewed set contains no relevant licensing-market records.

The following are three representative issue rows; they do not exhaust the claims or defenses.

C01 redirects attention from resemblance to ownership proof. C02 prevents reliance on restrictive language without examining later approval and its scope. C03 preserves both commentary and extent of copying without treating either as dispositive. Counsel can investigate these gaps before deciding whether to narrow allegations; the matrix does not manufacture missing evidence to justify that decision.

Common mistakes

• One row for the dispute. Separate works, actors, acts, rights, and periods so support for one allegation does not appear to support all.
• Comparing convenient versions. Match versions to disputed events and expose unresolved relationships.
• Treating resemblance as sufficient. Identify claimed expression, differences, potential exclusions, and the governing test.
• Omitting adverse permission evidence. Include approvals and amendments alongside restrictive clauses.
• Equating absence with disproof. Describe collection limits and assign follow-up before drawing conclusions.

Final quality check

• Every claim unit identifies its work version, defendant, act, right, and period.
• Material propositions have retrievable IDs and pinpoint citations.
• Supporting and adverse evidence remain visible.
• Ownership and permission analyses address actual works and uses.
• Registration and remedy questions have separately verified or disputed dates.
• Important exhibits and witness propositions have foundation questions recorded.
• Sources support legal propositions; controlling-authority gaps are assigned.
• Every material open issue has an owner, next action, milestone, and decision impact.

Frequently asked questions

Should each illustration or photograph have its own row?

Use a separate claim unit where separately asserted. Add linked rows when ownership, permission, or another issue needs independent treatment. Cross-reference shared evidence without merging distinct allegations.

Where should a long side-by-side comparison go?

Use a linked schedule with stable image regions, timestamps, or page references. Keep the matrix focused on material observations, contrary features, and unresolved analysis.

Can the matrix establish fair use?

No. It organizes factor-specific evidence and identifies gaps. Evaluate the complete record and governing authority rather than counting favorable cells.

Is the internal matrix ready to use as an exhibit?

Not automatically. Rule 1006 addresses summaries of voluminous admissible materials and requires access to originals or duplicates. Separately assess whether an evidentiary summary or illustrative aid is appropriate. Federal Rules of Evidence, Rules 1006 and 107. (uscourts.gov)
