IP infringement cover

IP infringement cover is a professional indemnity extension that indemnifies the insured against legal liability and defence costs arising from the unintentional infringement of a third party's intellectual property rights in the course of the professional business, including copyright, trade marks, design rights and related rights.

Definition §

IP infringement cover is an extension to a professional indemnity insurance policy that responds where the insured incurs civil liability for the unintentional infringement of a third party's intellectual property rights in the conduct of the professional business ^[1]. The covered rights typically include copyright and moral rights under the Copyright, Designs and Patents Act 1988, registered and unregistered trade marks under the Trade Marks Act 1994, and registered and unregistered design rights ^[2].

The extension is structured similarly to defamation cover: a general 'wilful breach' or 'intellectual property' exclusion carves the head of loss out of the main insuring clause and a specific extension reinstates cover for unintentional infringement, usually subject to a sub-limit and to a specific exclusion for deliberate infringement that interacts with the dishonesty exclusion.

IP infringement is a strict liability tort under English law — innocent infringement is generally still an infringement, although a defendant's lack of knowledge can be relevant to the remedies available ^[2]. The extension is therefore particularly important under a negligent act, error or omission wording, because the underlying tort does not require proof of negligence and may otherwise fall outside the trigger.

The cover is most relevant to firms whose work involves the creation, reproduction or distribution of content, designs or brand-related material — for example, designers, marketing agencies, publishers, software developers, architects and consulting firms producing branded deliverables.

Legal / Regulatory basis §

The principal statute governing copyright and related rights in the United Kingdom is the Copyright, Designs and Patents Act 1988, which sets out the categories of protected works, the acts restricted by copyright and the remedies available for infringement ^[2]. Trade marks are governed by the Trade Marks Act 1994. Patents are governed by the Patents Act 1977. Unregistered designs are governed by Part III of the 1988 Act and registered designs by the Registered Designs Act 1949.

For copyright, infringement is generally a strict liability tort: a defendant who unwittingly reproduces a substantial part of a protected work without licence may be liable for damages, an account of profits and injunctive relief ^[2]. Section 97 of the 1988 Act provides that no damages are payable where the defendant did not know and had no reason to believe that copyright subsisted in the work, although the claimant remains entitled to other relief; this defence is narrow and difficult to establish in practice for commercial professionals ^[2].

For trade marks, infringement under section 10 of the Trade Marks Act 1994 likewise does not require proof of negligence. Defences include honest concurrent use and certain comparative advertising rules.

For UK GDPR and Data Protection Act 2018 matters that relate to personal data, separate cover is normally found under cyber insurance and under the breach of confidentiality extension; these statutes are distinct from intellectual property ^[3][4].

The Insurance Act 2015 governs the contract of insurance in the usual way; previous IP claims and prior cease-and-desist correspondence are likely to be material circumstances for the purposes of fair presentation of the risk at placement ^[5].

How it works in practice §

When an allegation of IP infringement is notified, the cover analysis turns on whether the alleged conduct is within the scope of the extension and whether any deliberate-act exclusion applies. Most allegations begin with a cease-and-desist letter rather than the issue of proceedings, and notification at the cease-and-desist stage is usually required by the policy.

Defence strategy typically focuses on three questions. First, does the right exist and is it owned by the claimant? In copyright, this requires evidence of authorship, originality and subsistence; in trade marks, it requires the underlying registration or evidence of goodwill for passing-off. Second, has the insured's conduct fallen within the acts restricted by the relevant statute? In copyright cases this often turns on whether a 'substantial part' of the protected work has been reproduced. Third, are there any defences available — fair dealing for criticism, review or news reporting, parody, or honest concurrent use?

Many IP claims are resolved by undertaking, delivery up of infringing material and a modest monetary settlement; injunctive relief is the principal commercial concern of most rights holders. The extension typically responds to the legal costs of negotiating undertakings, the costs of redesign or relabelling where reasonably incurred to mitigate loss, and any damages or account of profits awarded or agreed in settlement, subject to the sub-limit.

The interaction with aggregation is significant in this context. A single design or template used across multiple client projects may give rise to multiple claims by different rights holders, and the question whether they 'arise from a single act or omission' or a series of related matters is fact-sensitive. The Supreme Court's reasoning in AIG Europe Ltd v Woodman on the meaning of related matters is the leading authority ^[6].

Common variations §

Copyright only. The narrowest formulation, covering infringement of copyright works under the 1988 Act but excluding trade marks, designs and other rights. Common in publisher PI.

IP except patents. The market norm. Patents are typically excluded because patent infringement claims are complex, expensive and frequently strategic; specialist patent infringement cover is available as a separate product.

Full IP including patents. Rare in standard PI but found in some technology and life sciences wordings, usually subject to a separate, lower sub-limit and to specific exclusions for known prior art.

Media liability suite. In policies sold to publishers and broadcasters, IP infringement sits alongside defamation cover, privacy infringement and contempt cover within an integrated media liability section.

IP excluded entirely. Many low-cost SME PI wordings exclude IP infringement altogether. Where the insured's deliverables include content, branding or designs, brokers should consider whether an extension is required or whether a stand-alone media or IP infringement policy is more appropriate.

Defence costs only. A minority of wordings respond to defence costs but not to indemnity for damages or licence-fee settlements. This is materially narrower and tends to leave the insured exposed to settlement payments.

Example §

An illustrative example: a marketing agency designs a brochure for a client that incorporates an image obtained from the internet without verifying the licensing position. The image is in fact subject to a stock-library licence, and the rights holder issues a letter alleging copyright infringement under section 17 of the Copyright, Designs and Patents Act 1988 ^[2]. The rights holder seeks £15,000 in licence fees on a punitive multiple and £8,000 in legal costs (illustrative only).

Under an IP infringement extension subject to a sub-limit of £1m, the cover responds to defence costs and to any damages payable, subject to deductible. The defence strategy focuses on whether the section 97 innocence defence might reduce damages, on negotiating a commercial settlement at the standard licence rate rather than a punitive multiple, and on whether the agency's own contractual chain (image supplier indemnity, client warranty) might provide partial recovery. The matter settles for £6,500 plus £4,000 defence costs, against the policy excess.

A free-standing claim for trade mark infringement on the same brochure would similarly fall within the extension, although the substantive defences would be different.
