IP 管理
免責事項: このスキルは、知的財産の概念と実践に関する一般的な教育情報を提供します。これは法的助言ではありません。組織に法的影響を与える可能性のある決定を行う前に、必ず資格のある IP 弁護士にご相談ください。
知的財産管理とは、組織の無形資産(発明、ブランドアイデンティティ、創作物、および機密ノウハウ)を特定、保護、活用するプラクティスです。ソフトウェア企業にとって、IP に関する決定は、競争上の優位性、オープンソース戦略、採用、M&A、および規制上のリスクに影響を与えます。このスキルは、適切な保護メカニズムの選択、オープンソースライセンス義務の遵守、特許および商標の管理、IP 損失を防ぐポリシーの構築など、IP のライフサイクル全体を網羅します。
このスキルを使用するタイミング
ユーザーが以下の場合に、このスキルをトリガーします。
- 新しいプロジェクトまたはリポジトリのオープンソースライセンスを選択する必要がある
- サードパーティのオープンソース依存関係のライセンスコンプライアンスを監査したい
- 商標出願を申請または調査している
- 企業または製品の営業秘密を保護する必要がある
- 請負業者または雇用契約における IP 譲渡条項を交渉またはレビューしている
- 企業の IP ポリシーを構築またはレビューしたい
- 特許、商標、著作権、および営業秘密の違いを理解する必要がある
- 内部ツールをオープンソース化するかどうかを評価している
以下の場合には、このスキルをトリガーしないでください。
- IP 条項を超える契約交渉(契約または法務業務スキルを使用)
- 商用ベンダー間のソフトウェアライセンス契約(SaaS 規約、エンタープライズ契約)
主要な原則
-
早期に保護する - IP 権は時間の影響を受けやすいことがよくあります。ほとんどの法域における特許出願は、先願主義に基づいて運用されます。商標権は、早期登録と一貫した使用によって強化されます。製品の発売まで IP 保護について考えないことは、競合他社が利用できるギャップを残すことを意味します。
-
オープンソースライセンスには実際の義務がある - オープンソースコードの使用は、法的リスクがないわけではありません。コピーレフトライセンス(GPL、AGPL)は、相互開示要件を課します。これらの義務を無視すると、プロプライエタリコードの強制的なオープンソース化、差止命令、および評判の低下につながる可能性があります。すべての依存関係にはライセンスがあります。それを契約として扱ってください。
-
営業秘密には積極的な保護が必要である - 営業秘密は、所有者が秘密を保持するために合理的な措置を講じている場合にのみ、法的に保護されます。それは、アクセス制御、NDA、機密保持ポリシー、および従業員トレーニングを意味します。パブリックな Slack チャンネルで不注意に共有されたり、請負業者を通じて漏洩したりした営業秘密は、永久に失われます。
-
雇用契約における IP 譲渡は明示的でなければならない - ほとんどの法域では、従業員が職務範囲内で作成した成果物は、デフォルトで雇用主に帰属しますが、「範囲」は曖昧です。請負業者の成果物は、デフォルトで譲渡されないことがよくあります。すべての雇用契約および請負契約には、明示的で広範な IP 譲渡条項が含まれている必要があります。買収前に過去の契約を監査してください。
-
定期的に監査する - オープンソースの依存関係ライセンスは、バージョン間で変更されます。新しい従業員は、以前の雇用主から IP を持ち込みます。請負業者は、不明確な所有権の下で成果物を作成します。定期的な IP 監査(少なくとも年 1 回、および M&A プロセスの前)は、まだ修正可能な問題を検出します。
コアコンセプト
IP の種類
| タイプ | 保護するもの | 期間 | 登録が必要ですか? |
|---|---|---|---|
| 特許 | 新規の発明およびプロセス | 出願から約 20 年 | はい(国または地域の特許庁) |
| 商標 | ブランド識別子:名前、ロゴ、スローガン | 無期限(更新と使用による) | 必須ではありませんが、登録により権利が強化されます |
| 著作権 | オリジナルの創作物(コード、ドキュメント、デザイン) | 著作者の生存期間 + 70 年(異なる) | 必須ではありません。作成時に自動的に発生します |
| 営業秘密 | 経済的価値のある機密ビジネス情報 | 無期限(秘密が保持されている限り) | 不要(登録すると開示されるため) |
いつどれを使用するか:
- 競合他社が独自に再発明できる可能性のある、斬新なアルゴリズムまたは技術的な方法には、特許を使用します。
- ブランドアイデンティティを保護し、顧客の混乱を防ぐために、商標を使用します。
- コードとドキュメントの逐語的なコピーを防ぐために、著作権を使用します(自動的に発生します。オープンソースライセンスは著作権の上に構築されています)。
- 機密性を維持することで価値を引き出し、簡単にリバースエンジニアリングできない、数式、データセット、プロセス、またはアーキテクチャには、営業秘密を使用します。
オープンソースライセンスのスペクトル
ライセンスは、寛容(義務が少ない)から強力なコピーレフト(相互開示が必要)まで多岐にわたります。スペクトル:
寛容 弱いコピーレフト 強いコピーレフト

自由に使用, + 特許付与, リンク OK, 変更は ネットワーク使用
帰属のみ + 特許平和 ただし、libへの変更は GPL でなければならない AGPL でなければならない
条項 = LGPL
BSL (Business Source License) および互換性マトリックスを含む詳細な比較表については、references/license-comparison.md を参照してください。
雇用における IP 所有権
デフォルトルール(法域によって異なります):
| 関係 | デフォルトの所有権 | 一般的な例外 |
|---|---|---|
| フルタイムの従業員 | 雇用主は雇用範囲内で作成された成果物を所有する | 雇用主の事業に関係なく、個人的な時間と個人的なリソースで作成された成果物 |
| 請負業者(独立) | 請負業者は、譲渡されない限り成果物を所有する | 書面による「職務著作物」条項または明示的な譲渡が必要 |
| インターン/学生 | しばしば不明確 - 契約で明記する必要がある | 学術的な成果物である可能性がある |

IP Management
Disclaimer: This skill provides general educational information about intellectual property concepts and practices. It is not legal advice. Always consult a qualified IP attorney before making decisions that may have legal consequences for your organization.
Intellectual property management is the practice of identifying, protecting, and leveraging the intangible assets of an organization - inventions, brand identity, creative works, and confidential know-how. For software companies, IP decisions affect competitive moats, open-source strategy, hiring, M&A, and regulatory exposure. This skill covers the full IP lifecycle: choosing the right protection mechanism, complying with open-source license obligations, managing patents and trademarks, and building policies that prevent IP loss.
When to use this skill
Trigger this skill when the user:
- Needs to choose an open-source license for a new project or repository
- Wants to audit third-party open-source dependencies for license compliance
- Is filing or researching a trademark application
- Needs to protect trade secrets in a company or product
- Is negotiating or reviewing IP assignment clauses in contractor or employment agreements
- Wants to build or review a company IP policy
- Needs to understand the difference between patent, trademark, copyright, and trade secret
- Is evaluating whether to open-source internal tooling
Do NOT trigger this skill for:
- Contract negotiation beyond IP clauses (use a contracts or legal operations skill)
- Software licensing agreements between commercial vendors (SaaS terms, enterprise contracts)
Key principles
-
Protect early - IP rights are often time-sensitive. Patent applications in most jurisdictions operate on a first-to-file basis. Trademark rights are strengthened by early registration and consistent use. Waiting until a product launches to think about IP protection means leaving gaps that competitors can exploit.
-
Open-source licenses have real obligations - Using open-source code is not free of legal risk. Copyleft licenses (GPL, AGPL) impose reciprocal disclosure requirements. Ignoring these obligations can result in forced open-sourcing of proprietary code, injunctions, and reputational damage. Every dependency has a license; treat it as a contract.
-
Trade secrets need active protection - A trade secret is only legally protected if the owner takes reasonable steps to keep it secret. That means access controls, NDAs, confidentiality policies, and employee training. A trade secret shared carelessly in a public Slack channel or leaked through a contractor is lost forever.
-
IP assignment in employment contracts must be explicit - In most jurisdictions, work created by an employee in the scope of their job belongs to the employer by default - but "scope" is ambiguous. Contractor work is often not assigned by default. Every employment and contractor agreement must contain an explicit, broad IP assignment clause. Audit historical agreements before an acquisition.
-
Audit regularly - Open-source dependency licenses change between versions. New hires bring IP from former employers. Contractors create work under unclear ownership. Regular IP audits - at least annually and before any M&A process - catch problems while they are still fixable.
Core concepts
IP types
| Type | What it protects | Duration | Registration required? |
|---|---|---|---|
| Patent | Novel inventions and processes | ~20 years from filing | Yes (national or regional patent office) |
| Trademark | Brand identifiers: names, logos, slogans | Indefinite (with renewal and use) | Not required, but registration strengthens rights |
| Copyright | Original creative works (code, docs, designs) | Life of author + 70 years (varies) | Not required; arises automatically on creation |
| Trade secret | Confidential business information with economic value | Indefinite (as long as kept secret) | Never (registration would disclose it) |
When to use which:
- Use patents for novel algorithms or technical methods that could be independently reinvented by a competitor.
- Use trademarks to protect brand identity and prevent customer confusion.
- Use copyright to prevent verbatim copying of code and documentation (it is automatic; open-source licenses are built on top of copyright).
- Use trade secrets for formulas, datasets, processes, or architecture that derive value from remaining confidential and cannot be reverse-engineered easily.
Open-source license spectrum
Licenses range from permissive (few obligations) to strong copyleft (reciprocal disclosure required). The spectrum:
Permissive Weak copyleft Strong copyleft
| | |
MIT Apache 2.0 LGPL GPL AGPL
| | | | |
Use freely, + patent grant, Linking OK, Modifications Network use
attribution + patent peace but mods to must be GPL must be AGPL
only clause lib = LGPL
See references/license-comparison.md for a detailed comparison table including
BSL (Business Source License) and compatibility matrix.
IP ownership in employment
Default rules (varies by jurisdiction):
| Relationship | Default ownership | Common exceptions |
|---|---|---|
| Full-time employee | Employer owns work created in scope of employment | Work created on personal time with personal resources, unrelated to employer's business |
| Contractor (independent) | Contractor owns the work unless assigned | Must have a written "work-for-hire" clause or explicit assignment |
| Intern / student | Often unclear - must be specified in agreement | Academic work may belong to the university |
Risk at M&A: Acquirers conduct IP due diligence. Missing assignments, unclear contractor agreements, and "moonlighting" projects create escrow holdbacks and deal risk. Audit before starting any fundraising or acquisition process.
Common tasks
Choose an open-source license
Decision matrix:
1. Do you want to allow proprietary use without sharing back?
YES -> Go to step 2
NO -> Choose GPL-3.0 (or AGPL-3.0 if server-side use matters)
2. Do you want a patent grant to protect users?
YES -> Apache-2.0 (preferred for corporate use)
NO -> MIT (simplest, most permissive)
3. Is this a library that will be linked into proprietary apps?
YES -> Consider LGPL-2.1 or MIT/Apache (LGPL allows proprietary linking)
NO -> MIT or Apache-2.0
4. Do you want a time-delayed open-source commitment (startup model)?
YES -> BSL (Business Source License) with a defined change date
5. Is this infrastructure software where SaaS competition is the concern?
YES -> AGPL-3.0 (requires disclosure even for network use)
Practical recommendations:
- Libraries intended for broad ecosystem adoption: MIT or Apache-2.0
- CLI tools and standalone applications: MIT, Apache-2.0, or GPL-3.0
- Server software where you want to prevent closed-source forks: AGPL-3.0
- Commercial open-core products: BSL with 4-year change date to Apache-2.0 or GPL
Audit open-source dependencies
Compliance audit process:
-
Inventory all dependencies - Run a software composition analysis (SCA) tool:
- Node.js:
license-checker,licensee, orfossa - Python:
pip-licensesorlicensecheck - Java/JVM:
license-maven-pluginorgradle-license-plugin - Go:
go-licenses - Multi-language: FOSSA, Snyk, or Black Duck
- Node.js:
-
Classify by risk tier:
Tier Licenses Action Green MIT, BSD-2, BSD-3, ISC, Apache-2.0 Approved; attribution required Yellow LGPL-2.1, LGPL-3.0, MPL-2.0, CDDL Legal review required; use restrictions apply Red GPL-2.0, GPL-3.0, AGPL-3.0, SSPL Block unless product is also open-source Unknown No license, custom license Block; contact maintainer or find alternative -
Generate NOTICE/CREDITS file - Include all required attributions. Apache-2.0 requires reproduction of the NOTICE file. MIT requires copyright notice.
-
Track license changes on upgrades - Licenses can change between major versions (e.g., BSL projects that have not yet reached their change date may tighten terms).
-
Automate in CI - Add SCA tool to CI pipeline. Fail the build on Red-tier licenses appearing without explicit approval.
File a trademark application
Process (US - USPTO; adapt for other jurisdictions):
-
Clearance search - Before filing, search the USPTO TESS database and common-law sources (web, app stores, domain registrations) for confusingly similar marks in the same class. A conflicting mark is grounds for refusal or opposition.
-
Identify goods/services class - Trademarks are registered per Nice Classification class. Software products typically use Class 42 (software as a service) and/or Class 9 (downloadable software). Registering in the wrong class provides no protection.
-
Choose filing basis:
- Use in commerce (1(a)) - Mark is already in use. Requires specimen showing use.
- Intent to use (1(b)) - Mark is not yet in use. Requires Statement of Use filing before registration is granted.
-
File the application - Via USPTO TEAS Plus (lower fee, stricter requirements) or TEAS Standard. Include: mark drawing, goods/services description, filing basis, specimen (if use-based).
-
Respond to office actions - Examiner may issue office actions requesting clarification or raising refusals. Respond within 3 months (extendable to 6).
-
Maintain the registration - File a Section 8 Declaration of Use between years 5 and 6 after registration, and renew every 10 years. Failure to maintain = cancellation.
International: Use the Madrid Protocol via WIPO to file in multiple countries with a single application based on a home-country registration or application.
Protect trade secrets
Trade secret protection program:
-
Identify what qualifies - Document all information that has economic value from being secret: source code, ML model weights, pricing algorithms, customer lists, roadmap, formulas. Create and maintain a trade secret register.
-
Access controls - Restrict access to need-to-know. Use role-based access in code repositories, databases, and documentation systems. Log all access.
-
Agreements:
- All employees sign NDAs and IP assignment agreements on day 1.
- All contractors sign NDAs before receiving any confidential information.
- Review agreements of new hires for non-competes or IP ownership conflicts from prior employers.
-
Physical and digital security - Encrypt sensitive data at rest and in transit. Enforce MFA on systems holding trade secrets. Monitor for and respond to data exfiltration alerts.
-
Offboarding procedure - Revoke access on the day of departure. Collect devices. Send a reminder letter referencing ongoing confidentiality obligations. For senior departures, consider exit interviews with counsel present.
-
Response to misappropriation - If a trade secret is leaked: preserve evidence, engage counsel immediately, assess Defend Trade Secrets Act (DTSA) claim in the US, seek injunctive relief before the information spreads further.
Manage a patent portfolio
Key decisions:
-
File or not? Patents are expensive ($15k-$50k+ per patent to grant in the US) and take 2-4 years. File only for inventions that are novel, non-obvious, useful, and represent a real competitive moat or defensive value.
-
Provisional vs. non-provisional - File a provisional patent application first ($3,200 small entity / $1,600 micro entity) to establish a priority date cheaply. You have 12 months to file the non-provisional application.
-
Defensive publication - If you do not want to file a patent but want to prevent competitors from patenting an invention, publish a defensive disclosure (e.g., via IP.com or the Linux Foundation's Open Invention Network).
-
Patent maintenance - US utility patents require maintenance fees at years 3.5, 7.5, and 11.5 after grant. Missing a fee abandons the patent. Track all deadlines.
-
Patent landscape analysis - Before entering a new technical area, commission a freedom-to-operate (FTO) analysis to identify blocking patents. Do not rely on in-house engineers to self-assess FTO risk.
Handle IP in contractor agreements
Minimum required clauses:
-
IP assignment - "All work product, inventions, and deliverables created by Contractor in connection with this agreement are hereby assigned to [Company], including all intellectual property rights therein."
-
Work-for-hire language - Include "to the extent any work product qualifies as a work made for hire under 17 U.S.C. § 101, it shall be a work made for hire."
-
Prior IP carve-out - Require contractor to list any pre-existing IP they intend to use in deliverables. Obtain a license to that IP, or prohibit its use.
-
Non-disclosure - Contractor agrees to keep all Company confidential information secret during and after the engagement.
-
No third-party IP - Contractor warrants that deliverables do not infringe third-party IP and do not incorporate GPL/AGPL code without written approval.
Red flags to investigate during contractor onboarding:
- Contractor previously worked on a competing product in the same technical area
- Contractor has a prior employer IP assignment that may cover the work
- Contractor intends to use their own open-source libraries under copyleft licenses
Create an IP policy
Minimum viable IP policy for a software company:
-
Scope - What IP the policy covers (code, inventions, trademarks, data, documents).
-
Ownership - All IP created by employees within the scope of employment belongs to the company. All IP created by contractors under agreement belongs to the company.
-
Open-source use policy - Approved license tiers (Green/Yellow/Red classification). Process for requesting approval of Yellow or Red licenses. Prohibition on committing AGPL/GPL code to proprietary repositories without legal review.
-
Open-source contribution policy - Process for contributing company code to external open-source projects. Requires manager + legal approval for non-trivial contributions.
-
Trade secret handling - Definition of confidential information. Access control requirements. NDA requirements for third parties.
-
Reporting obligations - Employees must disclose inventions to the company within 30 days of creation. Use a standard invention disclosure form.
-
Enforcement and review - Policy reviewed annually. Violations are a disciplinary matter.
Anti-patterns
| Mistake | Why it is wrong | What to do instead |
|---|---|---|
| Shipping without a license file | No license = "all rights reserved" by default; users cannot legally use the code | Always include a LICENSE file; even internal tools should have an explicit license |
| Using AGPL dependencies in a SaaS product without review | AGPL requires the entire application source to be disclosed to users who interact with it over a network | Audit with SCA tools; replace AGPL dependencies or obtain a commercial license |
| Treating trademark as permanent without maintenance | USPTO cancels registrations that are not maintained with use declarations and renewal filings | Calendar all trademark maintenance deadlines at registration; assign an owner |
| Letting contractors start work before signing an IP agreement | Work created before the agreement is signed may not be assignable retroactively | Block repository access and contract start until agreements are countersigned |
| Filing a patent without an FTO analysis | You may be infringing an existing patent in the same space, creating liability | Commission an FTO analysis before building in a new technical domain |
| Sharing trade secrets in public Slack channels or unprotected documents | Trade secret status is lost once publicly disclosed - permanently | Use access-controlled systems; label confidential documents; train employees |
