A proposal is a set of assumptions, and a contract makes them binding

A proposal is the first commercial document of an engagement. Its job is rarely the one its format suggests. It looks like a description of activity: methods, a timetable, a price. Its real work is to make the job's assumptions visible before anyone is committed to them. A dispute later then becomes an argument about a written line, not about what each side believed it heard. The contract then turns a subset of those assumptions into obligations, allocating the assumptions, the ownership and the rights of reuse. The default legal position does not allocate them the way a designer assumes.

The law begins with the maker rather than the payer. Making an allocation explicit therefore falls on the contract. The negotiation that produces it is also a documented source of error. This fifth of ten units, after the fourth priced the work, writes those assumptions down.

A proposal writes down the assumptions the work depends on

Raiffa (1982) treats negotiation as a question of structure before tactics. His claim is that understanding how the deal is built beats assembling a repertoire of moves. A proposal exposes that structure. It states which parts of the scope are fixed and which are negotiable, what the client must supply and by when, what counts as a change, when either side may stop, and whose access needs the work must name. Stating those facts costs less than discovering them later.

The proposal is also a pricing instrument. Maister (1993) locates profitability in leverage, utilisation, billing and pricing, and the client relationship. He argues that a firm must choose a strategy rather than drift into one. A proposal that names its assumptions is therefore a legal record and a commercial plan at once.

The default position puts the rights with the maker, not the payer

The clause designers most often skim decides who owns the result. It matters because silence has a legal answer. Bently and Sherman (2014) set out the law of patents, copyright, designs and trade marks, including subsistence, ownership and infringement. The rights arise under law; the act of commissioning does not by itself move them. A client who pays for a design often believes that payment and ownership go together. The doctrinal position is that they do not, unless the contract says so.

Bently, Sherman, Gangjee and Johnson (2026) examine ownership and entitlement. They cover who counts as an inventor, joint inventorship, employee inventions, and the remedies when the wrong person has applied. Much of ownership turns on categories a commissioning contract may never mention, which is the argument for settling it in writing. Menell (2019) adds the moving background. Intellectual property in its current technological context is being revised rapidly around new technology. A designer's rights therefore depend on a landscape that has to be checked for each engagement rather than assumed.

The negotiation has a structure, and the negotiator is a source of error

The conversation that fixes scope and price has a method with evidence behind it. Fisher and Ury (1981) set out principled negotiation. It distinguishes positions from interests, separates the people from the problem, invents options before choosing, and insists on objective criteria. The best alternative to a negotiated agreement is the standard for what to accept. That distinction turns a fight over the number of research sessions into a question about the decision the client must make.

The method is necessary because the negotiator is a documented source of error. Neale and Bazerman (1992) argue that a negotiator's frame, set on gains or on losses, biases how agreements are sought and evaluated. Bazerman, Curhan, Moore and Valley (2000) gather the biases, frames and multiple-issue relationships that shape an outcome. The warning is not that the client will behave badly. It is that the professional's own reasoning moves the deal.

One preparation claim is testable. Galinsky, Maddux, Gilin and White (2008) separated perspective taking from empathy. They found that perspective taking, the cognitive act of considering the counterpart's viewpoint, increased the discovery of hidden agreements and both created and claimed more value. Empathy was less advantageous and sometimes harmful. That argues for writing down the client's interests rather than for being agreeable in the meeting.

Perspective taking, not empathy, is what found the deal

The gas station study is the one to picture. Pairs of participants played buyer and seller of a service station. The buyer's authorised ceiling sat below the seller's floor, so no price-only deal existed, but a deal did: the buyer wanted managers to run the station, and the seller needed money for a sailing trip and a job on returning. Before negotiating, half the buyers were told to imagine the seller's thoughts and half the seller's feelings. About 76 per cent of the buyers told to consider the seller's thoughts reached the integrative deal, against about 40 per cent of the control group. The buyers told to consider the seller's feelings did not match them. The setting was a classroom role-play, so the case shows the mechanism under instruction rather than in a real contract negotiation.

A deal is worth more than its price

The negotiation literature has a measure the commercial documents usually omit. Curhan, Elfenbein and Xu (2006) developed and validated a four-factor model of subjective value in negotiation. It covers feelings about the outcome, the self, the process and the relationship. They found that subjective value predicted future negotiation decisions better than the economic outcome did. A contract signed at a good price by a client who felt the process was unfair is not a success on this evidence. The next engagement is decided partly on how this one felt.

Maister (1997) reaches the same place from the practice side. Professionalism means caring about the client's interest and the quality of the work rather than maximising short-term billings, so the contract and the relationship serve one end. A document that protects the firm's position at the cost of the relationship has mispriced the engagement it was meant to secure.

Contested question: is intellectual property a kind of property, and how far can a contract move the creator's rights?

This is the sharpest disagreement behind the unit, and the literature does not settle it. One position holds that intellectual property should not be treated as ordinary property at all. Lemley (2004) argues that doing so is an economic error, because the externalities at stake are positive rather than negative, so the case for policing free riding is much weaker than courts and scholars assume. Samuelson, Benkler, Post and Davis (2000) survey the successive strengthenings of intellectual property law in the digital economy and ask what commercial imperative justifies them. On this side, an ownership clause that maximises the client's rights is a contested allocation, not neutral housekeeping.

A second position places the creator at the centre. Ginsburg (2003) argues that the figure of the author, the human creator, is central to copyright and too often forgotten. Copyright makes sense only when its role in stimulating creative actors is recognised. The maker has a claim that does not evaporate when the money changes hands. A contract transferring everything therefore transfers something the law was built to protect.

A third position refuses the argument. Bently and Sherman (2014), and the ownership chapter in their current edition (Bently, Sherman, Gangjee and Johnson, 2026), treat ownership as legal rules to be applied rather than a philosophical question to be won. The contract allocates within what the law permits, and the duty is to state the allocation explicitly.

What would settle the disagreement is evidence the literature does not contain. That evidence would be cases or studies measuring what happens to creation and to reuse when rights are allocated differently in design engagements, and at what cost. Until then the defensible move is to name the allocation, the reuse rights and the derived-work rights in the document. It is also to say that the choice between the positions is being made rather than inherited.

The three positions are argued rather than tested, and none measures what different allocations do to creation or reuse. While the dispute is open, a designer should write the allocation and the reuse rights into the document and flag the choice. The strongest objection is that drafting cannot outrun the law, because a term that contradicts what the statute permits is unenforceable however carefully it is written.

Where the argument is heading

The direction of travel is towards contracts that name rights explicitly because the background law no longer supplies a safe default. Thaler v Comptroller-General of Patents (2023) shows the category being tested: the Supreme Court held that an inventor under the Patents Act 1977 must be a natural person, so owning the machine that generated an invention gives no right to the patent. Bently, Sherman, Gangjee and Johnson (2026) keep returning to ownership as a live question. Curhan, Elfenbein and Xu (2006) give the commercial reason to care: the relationship decides the next engagement as much as the price decides this one. The professional form that follows names the assumptions, the owner of each decision and the reuse rights.
