When a Biotech Partnership Breaks: Evidence, Ownership, and Compliance Records

Partnerships in the biotechnology sector are often formed on the promise of shared innovation, but they end in the complex reality of divergent interests, regulatory obligations, and fragmented data. When a collaboration between a research institution, a data processor, and a medical device manufacturer dissolves, the immediate operational concerns—access to samples, continuity of trials, or service handover—are overshadowed by a more fundamental question: what constitutes valid evidence of ownership, compliance, and control? The dissolution of a partnership is not merely a commercial event; it is a forensic and regulatory audit in real time. The quality of documentation held at the moment of termination determines whether a party can legally continue to use a dataset, maintain a patent filing, or defend against a regulatory inquiry. In the European Union, where the General Data Protection Regulation (GDPR), the AI Act, the Medical Device Regulation (MDR), and the Clinical Trials Regulation (CTR) create a dense web of accountability, the absence of a rigorous documentation strategy transforms a commercial dispute into a systemic legal risk.

The core challenge lies in the interplay between intellectual property rights, which are often designed to be exclusive and defensible, and data protection obligations, which are fundamentally rights-based and restrictive. A biotech partnership typically involves the exchange of biological samples, the generation of high-dimensional data, and the development of algorithms or therapeutic candidates. Each of these assets carries a different legal regime. Failure to maintain a clear, granular, and contemporaneous record of data provenance, consent status, and IP contribution is the single greatest predictor of liability when a partnership ends. This article examines the documentation that matters, distinguishing between EU-level regulatory frameworks and their national implementations, and explains how poor record-keeping converts operational ambiguity into legal exposure.

Data Provenance and the Chain of Custody

In a biotech partnership, data is rarely static. It flows from a donor to a processor, is enriched by a collaborator, and is transformed by an algorithm. When the partnership breaks, the chain of custody is the primary evidence of legitimacy. Under the GDPR, the concept of a “controller”—the entity determining the purposes and means of processing—is central. In a partnership, roles are often ambiguous. A university might be a controller for patient recruitment data, while a corporate partner becomes a controller for the derived genomic data used to train a predictive model. If the partnership dissolves without a clear record of when roles shifted or how processing activities were joint, the subsequent use of that data becomes legally precarious.

Mapping the Lifecycle of Biological Data

Documentation must begin at the point of collection. The provenance of a biological sample is not established by the sample itself, but by the legal and administrative framework surrounding its acquisition. This includes the original informed consent form, the patient information sheet, and the ethical approval (favorable opinion) from a competent ethics committee. Under the Clinical Trials Regulation (EU) No 536/2014, which applies to clinical trials conducted in the Union, the trial master file must be maintained and made available upon request. When a partnership ends, the ability to demonstrate that the data processing was consistent with the initial trial protocol is vital. Any deviation—such as using data for a new AI model that was not specified in the original consent—creates a compliance gap that becomes a weapon in a dispute.

The GDPR requires that personal data be processed lawfully, fairly, and transparently. If the legal basis for processing shifts from a public interest task (under Article 6(1)(e) for a university) to a legitimate interest of a private company (Article 6(1)(f)), this shift must be documented. Without a record of the legal basis assessment and the specific justification for the change, the data effectively becomes “toxic” upon dissolution; neither party can confidently assert the right to use it.

Furthermore, the technical logs of data access are as important as the legal contracts. Who accessed the dataset? When? From which IP address? Was the data copied to a local machine? In the context of the NIS2 Directive and the Cyber Resilience Act, maintaining audit trails is not just a best practice but a security obligation. If a partner exfiltrates data prior to termination, the forensic evidence of that exfiltration—server logs, access control lists—is the only recourse. Without it, the aggrieved party faces an evidentiary black hole.

Handling Special Category Data

Biotech partnerships almost invariably involve “special category data” under Article 9 of the GDPR, such as genetic data or health data. Processing this data requires a specific legal basis, usually explicit consent or a substantial public interest exemption. The documentation of this basis is non-negotiable. In Germany, for instance, the Bundesdatenschutzgesetz (BDSG) provides specific derogations regarding the processing of genetic data for employment contexts, but in a research partnership, the strictness of Article 9 prevails. If a partnership dissolves and one party wishes to retain the data for future commercialization, they must prove that the original consent covered such future use. If the consent form was generic—”for research purposes”—and the partner now intends to develop a commercial diagnostic tool, the legal basis is likely insufficient. The documentation of the consent process, including the version of the form used and the timestamp of the patient’s signature, becomes the deciding factor.

Technical Interoperability and Metadata

Ownership of data is often conflated with the ability to use it. If a partnership dissolves and the data is stored in a proprietary format controlled by one partner, the other partner may technically own the data but be unable to access it. Documentation must therefore include technical specifications and metadata standards. In the EU, initiatives like the European Health Data Space (EHDS) aim to standardize health data formats to facilitate interoperability. While the EHDS regulation is still in implementation, the principle it embodies is already relevant: data ownership implies the ability to port the data. If a partnership agreement lacks a clause on data export formats and the technical documentation to support it, the departing party faces a “digital hostage” situation.

Intellectual Property Boundaries in Collaborative R&D

Intellectual property (IP) is the currency of biotech. However, the ownership of IP generated during a partnership is rarely clear-cut. The distinction between background IP (what each party brought into the partnership) and foreground IP (what is created during the partnership) is the starting point, but the reality of AI-driven biotech blurs these lines. An algorithm trained on a partner’s proprietary dataset may generate insights that are mathematically dependent on both the code and the data. Disentangling this requires precise documentation of contributions.

Foreground IP and the “Joint Invention” Trap

Under EU patent law, and harmonized via the European Patent Convention (EPC), a “joint invention” exists if multiple persons contribute to the inventive step. If a data scientist from Company A and a biologist from University B collaborate on a novel biomarker discovery, and both contributed essential features to the invention, they may be joint owners. Without a pre-existing agreement specifying the division of rights, national laws apply, and they vary significantly.

In France, the “joint ownership” regime (Article L. 613-30 of the Intellectual Property Code) is restrictive. A joint owner cannot license the patent to a third party without the consent of the other owner, nor assign their share without offering it to the co-owner first. In Germany, the principle of Gemeinschaft (community) allows for more flexibility, but disputes often hinge on the specific contributions documented in lab notebooks or Git commit logs. If the partnership dissolves without a clear record of who invented what, the resulting IP is effectively frozen. No one can license it, and no one can improve it without risking infringement claims from the other.

Database Rights and the Sui Generis Protection

Beyond patents, the EU protects databases through the sui generis database right (Directive 96/9/EC). This right protects the investment in obtaining, verifying, or presenting the contents of a database. If a biotech company spends millions compiling a database of genomic sequences and clinical outcomes, that database is protected. However, if a partner contributes to the verification or presentation of that data, they may acquire rights to the database. The documentation of the investment—financial records, project plans, time logs—is essential to prove ownership. When the partnership breaks, the party claiming the database right must be able to demonstrate that the investment was theirs alone. If the records show shared funding for the data compilation, the database right becomes joint, complicating any future commercialization.

AI Models as IP Assets

The AI Act (Regulation (EU) 2024/1689) introduces new complexities. While the Act regulates the use of AI systems, it implicitly impacts IP ownership of the models themselves. A generative AI model trained on a partner’s data creates a derivative work. If the partnership agreement does not explicitly address the ownership of the model weights or the fine-tuned parameters, the legal status is ambiguous. In the United States, the “merger doctrine” might suggest that if the data cannot be separated from the model, the IP rights might merge. In the EU, the focus remains on the original data rights and the copyright of the training data. If the training data was used without a license that permits derivative works (e.g., a research exemption that does not cover commercial models), the resulting AI model may be an infringing object. Documentation of the data licensing terms—specifically whether they allow for “model training” and “derivative outputs”—is the firewall against IP invalidation.

Regulatory Commitments and Post-Trial Obligations

Biotech partnerships often operate within a regulatory framework that outlives the partnership itself. Clinical trials, medical device approvals, and market authorization create obligations that bind the parties, regardless of their commercial relationship. When a partnership dissolves, the transfer of these obligations is a critical documentation challenge.

Transfer of Sponsorship in Clinical Trials

Under the Clinical Trials Regulation (CTR), the “sponsor” of a trial has specific legal responsibilities. If a partnership dissolves and one party wishes to continue the trial, the transfer of sponsorship must be formally notified to the European Union Clinical Trials Information System (EUCTR) and approved by the relevant ethics committees and competent authorities. This is not a mere administrative update; it is a regulatory assessment of the new sponsor’s capability. The documentation required includes the new sponsor’s financial stability, insurance coverage, and technical competence. If the partnership dissolves acrimoniously and the departing partner refuses to sign off on the transfer of regulatory files, the trial may be suspended. The “Investigator’s Brochure” and the “Investigational Medicinal Product Dossier” must be physically transferred. If these documents are incomplete or if the chain of custody for the investigational product is broken, the regulatory authority (e.g., BfArM in Germany, ANSM in France) may invalidate the trial data.

Medical Device Regulation (MDR) and Technical Documentation

For partnerships involving medical devices or IVDs (In Vitro Diagnostics), the MDR imposes strict obligations on the “manufacturer.” If a partnership involves a hardware component and a software AI component, the dissolution requires a clear determination of who is the legal manufacturer. The technical documentation required by Annex II and III of the MDR is extensive. It includes design specifications, risk management files, and post-market surveillance plans. If the partnership breaks, the party that retains the “manufacturer” status must have access to the complete technical file. If the documentation is fragmented—e.g., the risk management file is held by Partner A and the clinical evaluation report by Partner B—neither party is compliant. The regulatory authorities do not recognize “joint” manufacturing in the sense of shared liability; they require a single point of contact and a complete file. Failure to assemble this file post-dissolution can lead to the withdrawal of the CE mark.

Pharmacovigilance and Safety Reporting

If the partnership involves medicinal products, the pharmacovigilance obligations under Regulation (EU) No 1235/2010 are continuous. The “Qualified Person for Pharmacovigilance” (QPPV) must have access to all safety data. If the partnership dissolves, the continuity of safety reporting is paramount. The documentation of adverse events, the “Periodic Safety Update Reports” (PSURs), and the risk management plan must be transferred seamlessly. If the records are kept in a shared database to which access is revoked during the dispute, the legal entity holding the marketing authorization is in breach of the law, facing potential fines or market suspension. The timeline for resolving such a transfer is tight; regulatory authorities expect notification within strict deadlines (often 15 days for changes in the QPPV).

GDPR Compliance Records as Evidence of Legitimacy

Under Article 30 of the GDPR, controllers and processors must maintain records of processing activities (ROPA). This document is often overlooked, but in a dispute, it serves as a sworn statement of the organization’s data handling practices. It maps data flows, purposes, and security measures. If a partnership dissolves and a dispute arises over data usage, the ROPA is the first document requested by a supervisory authority or a court.

The Role of the Data Processing Agreement (DPA)

When a biotech partnership involves one party processing data on behalf of another, a Data Processing Agreement (DPA) is mandatory under Article 28. The DPA specifies the subject matter, duration, and nature of processing. If the partnership ends, the DPA dictates the return or destruction of data. However, the DPA is often a boilerplate document. The actual implementation of the DPA is what matters. Did the processor actually delete the data? Can they prove it? The documentation of data deletion—cryptographic erasure certificates, deletion logs—is the only evidence that the processor has complied. Without it, the processor remains liable for data breaches involving that data, even years after the partnership ended.

International Data Transfers

Biotech partnerships often involve global players. If a partner in the US or UK is involved, data transfers are subject to strict safeguards. The “Schrems II” judgment and the subsequent European Commission Standard Contractual Clauses (SCCs) require a transfer impact assessment (TIA). This assessment documents the risks of access by foreign governments and the supplementary measures taken to mitigate them. If a partnership dissolves and the data is to be moved to a third country, the TIA must be reviewed. If the original TIA was insufficient or never conducted, the transfer is illegal. The documentation of the TIA is as important as the transfer mechanism itself.

National Implementations and Jurisdictional Nuances

While EU regulations provide a harmonized framework, national implementations create distinct legal environments. Understanding these nuances is critical when a partnership spans multiple member states.

Germany: The BDSG and Employee Data

In Germany, the BDSG supplements the GDPR, particularly regarding employee data and research. Section 27 of the BDSG allows for processing for research purposes even without explicit consent, provided certain safeguards are met. However, if a partnership dissolves and the data is to be used for commercial purposes rather than pure research, the BDSG exemption may no longer apply. The documentation must clearly delineate the boundary between “research” and “commercial development.” Furthermore, German labor law protects the “invention” of employees. If a researcher creates an algorithm as part of their employment, the IP rights automatically transfer to the employer (the university or company). If the partnership involves that researcher, the employer must document the invention disclosure to secure the IP. Without this, the researcher might retain rights, complicating the partnership’s IP claims.

France: CNIL and Health Data

The French CNIL (Commission nationale de l’informatique et des libertés) is particularly strict regarding health data. In France, the “HDS” (Hébergement de Données de Santé) certification is required for any entity hosting health data. If a partnership dissolves and one party wishes to host the data, they must be HDS certified. If they are not, the data cannot legally be transferred to them. The documentation of HDS certification and the audit reports is a prerequisite for any data handover. Additionally, French law on “fonds de recherche” (research funds) often imposes specific conditions on the ownership of results generated using public funds. The documentation of the funding source is essential to determine if the IP belongs to the public domain or the partnership.

Spain: AEPD and Consent Revocation

The Spanish Data Protection Agency (AEPD) emphasizes the right of the data subject to withdraw consent. If a partnership dissolves and the data is transferred to a new entity, the data subjects must be informed. If the original consent did not foresee this transfer, the data subjects have the right to object. The documentation of the communication strategy—how and when data subjects were informed—is crucial. In Spain, the lack of a clear mechanism for data subjects to exercise their rights post-dissolution is a frequent source of regulatory fines.

Forensic Readiness and Litigation Support

When a partnership breaks, the dispute often moves to litigation or arbitration. The ability to produce admissible evidence is then paramount. This requires a state of “forensic readiness”—the ability to preserve, collect, and analyze digital evidence without disrupting business operations.

Chain of Custody for Digital Evidence

In a legal dispute, the integrity of digital records is challenged. A lab notebook, a Git repository, or a database log must be proven to be authentic and unaltered. This requires a documented chain of custody. When a partner leaves, IT administrators must immediately preserve their digital footprint. This involves creating forensic images of their laptops and servers. If this is done without a documented legal hold process, the evidence may be inadmissible or violate privacy laws. The documentation of the forensic process—the “who, what, when, where, and why” of the data collection—is as important as the data itself.

Privilege and Legal Hold

Communications between the partners regarding the dissolution may be subject to legal privilege. However, business communications regarding the operational status of the data or IP are not. Distinguishing between the two requires careful documentation. When a legal hold is issued (a directive to preserve all relevant documents), it must be documented and communicated to all relevant personnel. If a partner deletes data after receiving a legal hold notice, that destruction of evidence (spoliation) can lead to severe sanctions from a court. The documentation of the issuance and acknowledgment of legal holds is a critical shield against accusations of sp
