Intellectual property due diligence: UK buyers’ support comparison

Compare Sprintlaw for quoted transaction support, LegalVision for membership-based lawyer access and LexisNexis UK for a buyer’s checklist—not an engagement to advise on your deal.[4][8][6] Use a rights-and-consent register to define the evidence you can gather and the questions an adviser needs to resolve.

Compare transaction advice, membership and checklist access

Sprintlaw

• Service scope: Sprintlaw, an online legal consultancy serving England and Wales (it states it is not an SRA-regulated law firm), advertises transaction support covering negotiations, due diligence and contract drafting.[4]
• Access model: It offers a free, no-obligation initial chat and a fixed-fee quote after reviewing your enquiry.[4]
• Price and commitment: Pricing is quote-based; ask Sprintlaw to confirm exact fees and cancellation and refund terms in writing.[4]

LegalVision

• Service scope: LegalVision offers business-sale assistance, including questions and document drafting and review.[8]
• Access model: Its membership advertises unlimited lawyer access.[8]
• Price and commitment: LegalVision describes a “low monthly fee”; ask it to confirm the exact price, contract length and cancellation and refund terms.[8]

LexisNexis UK

• Service scope: Its buyer checklist covers UK whole-business or selected-asset purchases, including searches, licences, software, employee and contractor evidence, and risk allocation.[6]
• Access model: Access requires sign-in or a Lexis+ trial; this is checklist access rather than an engagement for transaction advice.[6]
• Price and commitment: Ask LexisNexis UK to confirm the subscription price and paid contract duration; trials may be refused or terminated at any time.[6]

For transaction work, seek a scoped Sprintlaw quote.[4] For continuing legal access, investigate LegalVision’s membership.[8] For structured preparation, consider LexisNexis.[6] These are different purchases: compare the deliverables, not simply the payment model.

Build the rights register and link title evidence

Confirm what is being bought before requesting documents. Sprintlaw distinguishes buying selected assets from acquiring shares in the existing company, with its assets, liabilities and contracts.[4]

Use one register entry per material right or asset group. Suggested fields are:

• Asset, business use and relevant entity.
• Owned or licensed status, registered or unregistered status, and territory.
• Links to title evidence and supporting documents.
• Restrictions, consent questions, unresolved exceptions, reviewer and next action.

For coverage, LegalDocuments.co.uk’s England-and-Wales guide lists patents, trade marks, registered and unregistered designs, copyright, database rights, confidential information, trade secrets, domains and inbound and outbound licences.[5]

Link ownership claims to evidence. Request employment agreements, IP-assignment provisions, contractor assignments and confidentiality arrangements. The guide flags missing assignments from contractors or former employees as common title gaps.[5] Mark missing documents as exceptions rather than closing an entry on the strength of an asset list.

For patents, request a complete schedule of granted rights and applications, renewal and expiry dates, outstanding-fee status and territorial coverage. Cross-check ownership against UKIPO, EPO and relevant overseas records.[5] Technical patent analysis calls for patent-attorney input; a register match is not the full assessment described by the guide.[5]

For unregistered know-how and trade secrets, request confidentiality terms, access-control records and IT-security evidence: these assets are not ordinarily visible on public registers.[5]

Track licence restrictions and consent questions

For each material inbound or outbound licence, link the agreement and record the rights received or granted, third-party rights, relevant restrictions and the consent question.[1][5] Add a reviewer and space for evidence of resolution. The IPO’s knowledge-asset guidance addresses public-sector and university contexts; use it as context, not a universal private-acquisition standard.[1]

Frame the question around the deal structure. For an asset purchase, Sprintlaw recommends addressing contract transfers in the sale agreement; assignment or novation documents may be needed for key contracts and IP.[4] For a share purchase, review change-of-control terms rather than assuming consent questions disappear.[5] Ask which restrictions apply to the proposed transaction and intended use.

Fictional example: An essential software licence contains a transfer restriction whose application is unresolved. The buyer links the agreement, records the clause and planned use, and assigns the question to the legal adviser. The entry stays open while the adviser assesses whether consent is needed and supporting evidence is obtained.

Separate preparation from specialist findings

Gather documents, index assets, flag missing evidence, extract contract clauses and track the seller’s responses. This prepares the evidence for the ownership and licence checks described in LegalDocuments.co.uk’s guide.[5]

Keep distinct statuses: “document supplied” is not “ownership verified”, and “consent clause located” is not “consent obtained”. Record the adviser’s conclusion separately from the underlying evidence.

• Escalate exceptions: missing assignments, conflicting ownership, lapsed rights, restrictive licences, open-source compliance concerns and disputes warrant specialist assessment.[5]
• Match expertise to the question: route technical patent issues to a patent attorney, and title, licence interpretation and deal protections to advisers with relevant IP and transaction experience. The England-and-Wales guide describes support proportionate to deal size and IP importance.[5]

The IPO describes formal diligence as led or signed off by a qualified patent attorney or IP professional.[1] Ask advisers to scope and price any freedom-to-operate assessment separately: the IPO describes it as a legal assessment that may cost extra, with a full search unnecessary for some projects.[1]

Turn exceptions into completion decisions

Give each material open issue an exception brief: the business activity depending on it, missing or conflicting evidence, the adviser’s question, proposed action, owner, timing and proof needed to close it.

Request settled, ongoing and threatened dispute histories, cease-and-desist correspondence and existing freedom-to-operate opinions. Ask advisers to assess potential infringement by the target and infringement of its rights by others.[5]

Findings can inform warranties, disclosures and price; identified risks may warrant a retention, specific indemnity or remediation before completion.[5] Ask how the response should appear in the sale agreement’s payment and completion provisions.[4]

• Should a missing assignment be secured before completion?
• Should necessary consent become a completion requirement?
• What protection is appropriate for an unresolved dispute?

What to confirm with each provider

Send the register and exception list with your enquiry. For Sprintlaw and LegalVision, deal-specific scope and specialist inclusions require confirmation beyond their general service descriptions; for LegalVision, also confirm constituent-nation coverage.[4][8]

• Deliverables: Request a reviewed register, exceptions report and recommendations on consents and completion protections.
• Specialists and exclusions: Establish who handles IP and patent questions, and which tasks cost extra.
• Fees and commitment: Obtain the total price, contract term and exit terms in writing.
• Completion work: Ask the adviser to confirm clause wording, applicable registry fees and assignment filing deadlines for the transaction.
