In any transaction involving a technology company, a consumer brand, a pharmaceutical business, or a content platform, intellectual property is not one section of the due diligence checklist. It is the primary value driver — often accounting for the majority of the enterprise value being acquired.
Yet IP due diligence is routinely underfunded, compressed, or treated as a compliance exercise rather than a commercial risk assessment. The consequences of this approach play out in post-closing disputes, warranty claims, and — in the worst cases — post-acquisition injunctions that shut down the business being operated.
Here is a practitioner-level framework for what IP due diligence must cover.
The Four Foundational Questions
Every IP due diligence exercise is structured around four questions: What does the company own? Is ownership clean? Is the IP enforceable? What third-party risks exist?
These four questions apply across every category of IP — trademarks, patents, designs, copyright, domain names, trade secrets, and data. The answers to each question, for each asset category, determine whether the IP portfolio is an asset that supports the acquisition price or a liability that requires price adjustment, indemnification, or pre-closing remediation.
Trademark Due Diligence
The trademark workstream examines: registration status (active, renewed, in correct classes); ownership (are marks registered in the correct entity’s name or in a founder’s personal name?); chain of title (all prior assignments recorded at the Trade Marks Registry?); licence arrangements (quality control provisions adequate, no undisclosed exclusivities binding the acquirer?); and pending adversarial proceedings (opposition cases, cancellation actions, infringement suits received).
The most common defect in Indian startup transactions is marks registered in the founder’s individual name rather than the company. This is not a trivial paperwork issue. If the marks are not formally assigned to the company before closing, the company technically does not own its brand. An investor or acquirer who closes without resolving this inherits the risk that the founder could later assert ownership.
International trademark coverage is equally important for businesses with cross-border operations. Gaps in Madrid Protocol coverage for key export markets, or missing national registrations in critical territories, are material risks for brands with international revenue.
Patent Due Diligence
The patent workstream covers: all patents and applications identified and status confirmed; inventor records reviewed and employment agreements confirmed to establish that employer (company) ownership was properly created; maintenance fee status (no patent lapsed through missed annuity payments); pending prosecution milestones (FER response deadlines, hearing dates); and — most critically — freedom-to-operate analysis.
A freedom-to-operate analysis determines whether the target company’s current or planned products and processes infringe any third-party patent rights in the relevant commercial markets. An acquirer who completes a transaction without conducting FTO inherits all the target’s infringement liability. A post-acquisition patent injunction can halt operations in a core product line.
Copyright Due Diligence
The copyright workstream is most consequential for software companies, content platforms, and creative agencies.
For software: all code must be reviewed for open-source components. Open-source licences (GPL, LGPL, AGPL) impose conditions on commercial use — some require the entire codebase to be made available publicly if the software is distributed. Discovery of GPL-contaminated code in a commercial product after closing is a significant liability.
Contractor assignments are a universal risk area. Every developer, designer, or creative professional who worked as a contractor — and who was not required to sign a written copyright assignment — legally retains the copyright in what they created. Verbal agreements are not valid assignments under Section 19 of the Copyright Act.
For content platforms: rights clearances for all licensed content, sub-licensing rights, and music synchronisation licences must all be verified.
Trade Secrets and Confidential Information
In software, AI, and platform businesses, the algorithm, model, or data architecture may be the most commercially valuable asset in the company — with no formal IP registration. Protection exists only through confidentiality.
The DD workstream here covers: adequacy of NDAs with employees and contractors; controls on who has access to the most sensitive technical assets; whether departing employees are bound by ongoing confidentiality obligations; and compliance with data protection law — particularly DPDPA 2023 obligations regarding customer data.
From DD to Transaction Documentation
IP due diligence findings directly shape three elements of transaction documentation.
Purchase price: IP valuation affects the allocation of enterprise value. Defective or contested IP assets warrant price adjustment or escrow arrangements.
Representations and warranties: The seller warrants the accuracy of IP disclosures. IP warranty breaches are among the most litigated post-closing claims. Scope, survival period, and caps on IP indemnities require careful negotiation.
Conditions precedent: Material IP defects — unresolved founder-to-company transfers, lapsed core marks, active injunction proceedings — may be structured as conditions to completion that must be resolved before the deal closes.
The cleanest transactions are the ones where IP housekeeping has been done continuously throughout the company’s life — not assembled hastily in the two weeks before the data room closes.
