Separability (Collateral)
Definition
Separability is the degree to which an intangible asset can be sold, licensed or otherwise transferred on its own, apart from the business that owns it. As a lender test — the separability collateral test — it asks a blunt question: if the borrower failed, could this asset be lifted out and disposed of to a third party, or is it so bound into the going concern that it has no independent realisable value? Separability is one of the three tests, alongside saleability and legal strength, that lenders weigh together and apply to a conservative orderly-disposal value to decide how much they will advance. It matters because a lender's fallback on default is disposal, and an asset that cannot be detached from the business cannot be sold to repay the debt. Registered rights tend to score well: a patent identified by number, or a registered trade mark, can be assigned by a clean legal instrument and transferred to a buyer. Deeply embedded assets — an assembled workforce, integrated internal processes, or goodwill inseparable from the trading entity — score poorly because no buyer can acquire them in isolation. Licensed IP generating attributable royalty income is attractive precisely because the income stream and the underlying right can be conveyed together. The separability collateral test also shapes how the asset is charged: a fixed charge or a legal mortgage over an identifiable, separable right (for example, by patent number) gives a lender far stronger security than a floating charge over a shifting pool. In UK practice, an SME founder seeking IP-backed lending should expect a valuer working to IVS 210 to consider separability when framing an orderly-liquidation premise, and a credit team to treat a genuinely separable, transferable right as materially better security than know-how that walks out of the door with the team.

Concepts that frequently appear alongside Separability (Collateral) in practice.
Saleability is how readily an intangible asset could be sold or licensed to realise cash, particularly on a default when a lender must dispose of security within a constrained timeframe. Where separability asks whether an asset can be detached from the business at all, the saleability of an intangible asset asks the harder market question: is there an identifiable pool of buyers, a functioning secondary market, and a realistic prospect of achieving value within an orderly-disposal window rather than a distressed fire sale.
Legal strength is the extent to which the owner holds clean, unencumbered and enforceable title to an intangible asset, so that a lender could take valid security over it and realise value without a title dispute. In lending, the legal strength of IP collateral is the third of the three tests — with separability and saleability — that a lender weighs together and applies to a conservative disposal value to decide how much to advance.
Collateral suitability is a lender's assessment of whether an asset can serve as dependable security for a loan, judged by how readily and reliably its value could be realised if the borrower defaulted. For intangible assets, collateral suitability is not a single number but a considered judgement formed by weighing three lender tests together — separability (can the asset be sold or licensed apart from the business), saleability (how readily it would find a buyer on default), and legal strength (whether title is clean and enforceable) — and applying that judgement to a conservative, orderly-disposal value.
An assignment by way of security is the legal mechanism used to create a legal mortgage over intellectual property, whereby the borrower transfers title to the IP to the lender as collateral while retaining an equitable right to have it reassigned once the debt is repaid. Unlike an outright assignment, an assignment by way of security is conditional and reversible, and it is almost always accompanied by a licence-back so the borrower can carry on using the assigned patents, trade marks or designs in the ordinary course of business.
A security interest over a specific, identified asset that prevents the borrower from dealing with or disposing of the charged asset without the lender's consent. Fixed charges attach to assets such as land, buildings, specific plant and equipment, or identified intellectual property rights.
Orderly liquidation value is the estimated proceeds an asset would realise if sold within a reasonable marketing period by a willing but compelled seller, rather than in a rushed distress sale. It sits between market value and forced sale value, and it is the premise a prudent lender leans on when sizing security against intangibles.
IVS 210 is the International Valuation Standards asset standard that governs how intangible assets are valued, and it is the framework a credible IP valuation for lending must follow. When a lender advances against patents, trade marks or other intangibles, it relies on a valuation prepared to a recognised standard so that the figure supporting the loan-to-value can withstand credit scrutiny, and IVS 210 intangible assets is that standard.
A licence-back is a licence granted by a lender back to a borrower that has assigned its intellectual property as security, permitting the borrower to continue using that IP in its business for the life of the loan. A licence-back arrangement is the practical companion to a legal mortgage or an assignment by way of security: the borrower transfers title to the lender as collateral, and the lender immediately licences the rights back so day-to-day operations, manufacturing and sales carry on uninterrupted.

What advance rate applies to intangible assets?
There is no fixed rate. Intangible assets are valued case by case, with broad-market lending around 20–40% of appraised value and insurance-backed facilities reaching up to roughly 50%.
Read full answer →What is a collateral suitability assessment?
A collateral suitability assessment judges how good an intangible asset is as loan security by testing its separability, saleability and legal strength against an orderly-disposal value to set the loan-to-value.
Read full answer →Why do lenders test separability, saleability and legal strength?
Because on default a lender must recover value from the IP alone. Separability, saleability and legal strength together decide whether the asset can be isolated, sold and enforced — which sets the loan-to-value.
