Unlike the Trade Secrets Act, the Patent Act uses the fruits of the poison tree doctrine in a much more limited and controversial way. Patent infringement is largely defined by the scope of the claims and the duration of the patent. Only products or acts containing each element of a claim or its equivalents are considered infringing.29 Accordingly, courts will not prescribe final products that do not contain all the elements of the claim, even if they were made using the patented invention as a model and even if the products were forged in the laboratory and were modified only before manufacture, that they do not infringe.30 Indeed, “designing” a patent by starting with the patented product and then modifying it to the point of avoiding infringement is not only not prohibited, but is actively encouraged.31 All legal doctrines fight against the limits of causality, and intellectual property law is no exception. Current intellectual property regimes apply the fruits of the poisoned tree doctrine with apparently few rhymes or reasons. By understanding when and why we want to use such a doctrine, not only can we understand otherwise confusing aspects of intellectual property law, such as advance decisions on trade secret law and direct access fees in patent law, but we can also identify legal rules that do not make much sense, such as the inability to divide the damage caused by design patents or the excessive control that copyright gives over derivative works. Such evidence is in principle not admissible before the courts.

[6] For example, if a police officer conducted an unconstitutional (Fourth Amendment) search of a house and received a key to a post office locker and evidence of a crime came out of the record, that evidence would most likely be excluded under the poisoned tree fruit legal doctrine. However, the testimony of an illegally discovered witness would not necessarily be excluded on the basis of the “depreciation doctrine”[7], which allows certain evidence or testimony to be admitted in court if the link between the unlawful conduct of the police and the resulting evidence or testimony is sufficiently weakened. For example, a witness who testifies freely and voluntarily is a sufficient independent intervening factor to sufficiently “weaken” the link between the illegal discovery of the witness by the government and the voluntary testimony of the witness himself.

The rise of the doctrine of transformative use into fair use has moved copyright law in the right direction here by apologizing for many uses that would otherwise have triggered the fruit of the poisoned tree doctrine. See, for example, Authors Guild v. Google, Inc., 804 F.3d 202 (2d Cir.

2015) (application of the doctrine of transformative use to cases of copyright infringement by authors); Bill Graham Archives v. Dorling Kindersley Ltd., 448 F.3d 605 (2d Cir. 2006) (application of the doctrine of transformative use in a poster copyright case); Pierre N. Leval, Towards a Fair Use Standard, 103 Harv. L. Rev. 1105 (1990) (provides an overview of the interaction between transformative use and fair dealing doctrines). If the primary evidence was obtained illegally but is admissible except in good faith, their derivatives (or “fruits”) may also be admissible. Many legal doctrines struggle against the limits of causality. The world is a complex and interconnected place. We can follow the echoes of actions through an almost infinite chain of probable or at least possible circumstances.

When you drove your car in mine, you damaged it, which forced me to pay the costs of towing and repair. This causal chain is quite simple and something for which the law will certainly compensate me. But you also made me take several days off work, so I wasn`t paid. Perhaps the law will also compensate me if it considers that the damage is sufficiently foreseeable. But let`s say that while I was without a car, I lost focus on a long-term work project, and the offer I submitted wasn`t as good as it could have been. My employer lost the contract as a result, and the company`s profits were lower than they would otherwise have been. This, in turn, meant that the share price had fallen and the retirees who held that stock had less money than they would otherwise have. Stress caused by money problems even led one of these retirees to suffer a heart attack. It is at least possible – although less and less likely – that each of these claims is true as a matter of causal conclusion. None of these things would have happened without the car accident. But the law will not allow me or those around me to recover from all these losses, even if we can prove that they occurred. Rather, the doctrine of immediate ground is intended to limit plaintiffs to remedies that were caused both by the defendant`s actions in an aimless sense and that were sufficiently direct and therefore foreseeable.9 It follows that the law cannot – and probably cannot – completely reverse – the harm caused by various offences.

Instead, an attempt is made to reconcile efforts to heal injuries with the practical limitations of tracing causal waves as much as possible. Trade secret law also applies the fruit of the poisoned tree doctrine in the temporal sense. Trade secrets are protected only until they are made public.24 Nevertheless, courts sometimes issue injunctions that prevent the defendant from using the secret or the products developed with it, even after the secret has been known. These “advance orders” are available to applicants who have finally published or disclosed their secret after it has been misappropriated.25 For example, let`s say Anne has a secret that she markets. Let`s further assume that it takes Anne two years to develop the secret of the product launch, after which the secret is revealed. If Benjamin steals Anne`s idea during the development process (for example, after a year), Benjamin will be able to hit the market a year earlier than if he had waited for the information to become public.
