# Skill: Draft Opposition to Summary Judgment in Patent Infringement Litigation

## 1. Subject-matter triage
- Identify the asserted patents, challenged claims, accused products, and the exact summary-judgment theories being advanced.
- Read the claim construction order first; the opposition must track the court’s constructions, not the parties’ preferred meanings.
- Determine whether the motion attacks infringement, noninfringement, invalidity, damages, or more than one theory, and organize the response in the same order as the motion.

## 2. Failure modes the skill is correcting
- Treating summary judgment as a persuasion exercise instead of a record-driven dispute analysis; the brief must identify specific evidence creating a genuine dispute of material fact.
- Responding in the abstract rather than element-by-element under the governing claim constructions.
- Ignoring expert reports or using them only as background, when technical and damages issues often turn on expert testimony tied to the record.
- Overlooking deposition excerpts, product documents, source materials, testing data, and admissions that can defeat a claimed absence of dispute.
- Failing to connect each factual dispute to the legal standard for Rule 56 and the patent-specific issues actually framed by the motion.
- Drafting an opposition that reads like a stand-alone merits brief rather than a focused answer to each asserted basis for judgment.
- Stating legal conclusions without naming the controlling authority that supports them.

## 3. Legal frameworks / domain conventions that apply
- Federal Rule of Civil Procedure 56 governs summary judgment: the movant must show no genuine dispute as to any material fact and entitlement to judgment as a matter of law.
- The nonmovant may rely on materials that would be admissible in substance, even if not presented in trial form, so long as the cited record can support a jury finding.
- Patent infringement must be analyzed against the operative claim construction order; the question is whether a reasonable jury could find each claim limitation satisfied under the construed language.
- Genuine disputes often arise from competing expert opinions, witness admissions, product specifications, test results, and other technical record evidence.
- If the motion implicates claim validity or damages, use the governing statutory, evidentiary, and procedural authorities as stated in the record or in generally recognized practice.
- Every proposition in the opposition should be anchored to authority by name and section, rule, or case, rather than asserted as a bare conclusion.

## 4. Analytical scaffolds
- Motion mapping: list each distinct ground for summary judgment and answer it in the same sequence, so no theory is left unattended.
- Claim-by-claim analysis: for each asserted claim, apply the court’s construction and test each disputed limitation against the cited record.
- Limitation-by-limitation proof: where the movant argues a limitation is missing, identify the exact evidence from experts, deposition testimony, technical documents, or admissions that supports the opposite inference.
- Record-to-opinion linkage: pair every expert statement with the underlying record material that supports it, and explain why the contrary expert view does not eliminate a triable issue.
- Materiality analysis: explain why each disputed fact matters to infringement, validity, or damages under the governing theory, rather than merely describing a disagreement.
- Rule 56 framing: show that the record would allow a reasonable jury to return a verdict for the nonmovant on the challenged issue.
- Authority discipline: cite the controlling rule, case, or other authority for each legal standard and avoid uncited doctrinal assertions.

## 5. Vertical / structural / temporal relationships
- Track the relationship among the claim construction order, the expert reports, the deposition record, and the accused-product evidence; the opposition should show how those materials interact, not treat them as isolated exhibits.
- Preserve the sequence of analysis from the motion, then the factual record, then the legal standard, so the court can see why judgment should be denied on the existing record.
- If the briefing guidelines impose formatting, citation, or length constraints, conform exactly and keep the response within those bounds.

## 6. Output structure conventions
- Use an opposition-brief structure with a compact introduction, a Rule 56 standard section, an argument section keyed to each motion ground, and a short conclusion requesting denial.
- Include a focused statement of genuinely disputed facts or a record-based counterstatement if the briefing guidelines call for it.
- Use claim- or issue-specific subheadings that mirror the motion’s structure and make it easy to match each response to the corresponding argument.
- Cite record materials with precision and identify the source of each factual assertion.
- Keep the tone courtroom-appropriate: assertive, technical, and tethered to the record, without rhetorical overstatement.
