Draft Complaint Patent Infringement

Skill: Draft Federal Patent Infringement Complaint

1. Subject-matter triage

• Determine the asserted patents, accused products, target forum, filing posture, and whether the source set supports a complaint alone or a complaint plus memo.
• If multiple patents, accused products, inventors, assignees, or notice events are in play, enumerate them first and map each to the relevant claim, product, and factual predicate before drafting.
• If the matter is intended for a specific district, conform the complaint to that district’s local patent practice and any filing-side prerequisites reflected in the source documents.
• Treat the complaint as the primary deliverable and the cover memorandum as secondary; the complaint must be drafted first and must stand on its own.

2. Failure modes the skill is correcting

• Pleading venue under the patent venue statute without facts showing either incorporation-based venue or acts of infringement plus a regular and established place of business in the district.
• Treating general commercial presence, registration, or remote sales as enough for venue without the physical-place allegations the statute requires.
• Failing to trace ownership or exclusive rights through the full chain of title, including intermediate assignments or predecessor entities, so standing is vulnerable at filing.
• Omitting claim-by-claim and product-by-product linkage, leaving the pleading too generic to support the asserted infringement theory.
• Neglecting willfulness allegations where the source documents show pre-suit notice and post-notice continuation of accused conduct.
• Drafting only the complaint and omitting the cover memorandum that explains strategic choices, venue posture, chain-of-title posture, and expected defenses.

3. Legal frameworks / domain conventions that apply

• Subject-matter jurisdiction: 28 U.S.C. § 1338(a) for patent claims.
• Venue: 28 U.S.C. § 1400(b); venue lies where the defendant resides or where it has committed acts of infringement and has a regular and established place of business.
• Standing and ownership: the plaintiff must own the asserted patent or hold enforceable exclusionary rights at filing; trace title through each assignment or transfer reflected in the source set.
• Patent infringement pleading: identify the asserted patent numbers, the accused products or methods, the infringing acts, and the claims implicated.
• Willfulness and enhanced damages: pre-suit knowledge plus continued infringement supports a willfulness theory; reference the governing patent damages framework, including 35 U.S.C. § 284 and the prevailing pleading practice.
• Injunctive and other relief: plead requested remedies consistent with patent-law remedies and the factual record.
• Local patent rules and docketing conventions: where applicable, align the complaint and any memo with the forum’s expected patent filing format and any disclosure or certification practice.
• If the source documents include parallel-forum or coordination facts, preserve them in the memo only if they bear on filing strategy, risk, or sequencing.

4. Analytical scaffolds

• Caption and parties: identify the court, parties, entity type, state of incorporation, and principal place of business where supported.
• Jurisdiction and venue: plead 28 U.S.C. §§ 1338(a) and 1400(b) with facts tied to the target district, not boilerplate alone.
• Patent ownership: build a clean title narrative from inventor or predecessor through each transfer to the plaintiff; if a link is unclear, flag it in the memo and avoid overstatement in the complaint.
• Infringement theory: pair each asserted claim set with each accused product or method and allege direct infringement with enough specificity to anchor later claim-chart work.
• Knowledge and willfulness: use the notice timeline in the source documents to allege awareness, continued activity, and the basis for enhanced-damages and case-management requests.
• Relief: include damages, reasonable royalty or other patent damages theories supported by the record, costs, fees where appropriate, and injunctive relief if facts support irreparable harm and inadequacy of legal remedies.
• Memo function: explain why the pleaded venue theory is sustainable, what standing issues were checked, what factual gaps remain, and what defenses are likely to be raised.

5. Vertical / structural / temporal relationships

• Align every accused product to the asserted patent claims and to the relevant infringement time period; do not merge distinct products or distinct notice events into one undifferentiated allegation.
• Track the chronology from patent issuance and ownership transfer through pre-suit notice and post-notice conduct, because timing often controls standing, willfulness, and damages posture.
• Distinguish forum facts that support filing in the chosen district from facts that merely show nationwide sales or corporate presence elsewhere.
• Where the source set contains multiple potential plaintiffs, assignees, or related entities, verify who is the proper plaintiff at filing and who, if anyone, should be described only as a predecessor or transferor.
• Where multiple forms of relief are requested, separate the factual basis for damages from the factual basis for injunction and fees.

6. Output structure conventions

• Complaint: use a court-standard federal complaint format with caption, introduction, jurisdiction, venue, parties, factual allegations, asserted patent sections, infringement counts, willfulness allegations if supported, and prayer for relief.
• Complaint drafting should be substantive, not merely explanatory; it must contain operative allegations rather than references to analysis to come.
• Cover memorandum: concise strategic memo that explains venue support, title review, infringement theory, willfulness basis, anticipated defenses, and any filing or coordination considerations.
• If any material factual gap remains, identify it in the memo and explain the litigation risk it creates; do not over-plead unsupported certainty in the complaint.
• Before finalizing, confirm that the complaint file is the primary completed deliverable and that the memorandum follows only after it, with both files non-empty and containing operative content.
