In common-law legal systems, laches is a lack of diligence and activity in making a legal claim, or moving forward with legal enforcement of a right, particularly in regard to equity. It is an unreasonable delay that can be viewed as prejudicing the opposing party. When asserted in litigation, it is an equity defense, that is, a defense to a claim for an equitable remedy. It is often understood in comparison to a statute of limitations, a statutory defense, which traditionally is a defense to a claim "at law".
An injunction is an equitable remedy in the form of a special court order that compels a party to do or refrain from specific acts. "When a court employs the extraordinary remedy of injunction, it directs the conduct of a party, and does so with the backing of its full coercive powers." A party that fails to comply with an injunction faces criminal or civil penalties, including possible monetary sanctions and even imprisonment. They can also be charged with contempt of court.
In the field of jurisprudence, equity is the particular body of law, developed in the English Court of Chancery, with the general purpose of providing legal remedies for cases wherein the common law is inflexible and cannot fairly resolve the disputed legal matter. Conceptually, equity was part of the historical origins of the system of common law of England, yet is a field of law separate from common law, because equity has its own unique rules and principles, and was administered by courts of equity.
A lawsuit is a proceeding by one or more parties against one or more parties in a civil court of law. The archaic term "suit in law" is found in only a small number of laws still in effect today. The term "lawsuit" is used with respect to a civil action brought by a plaintiff who requests a legal remedy or equitable remedy from a court. The defendant is required to respond to the plaintiff's complaint or else risk default judgment. If the plaintiff is successful, judgment is entered in favor of the plaintiff, and the Court may impose the legal and/or equitable remedies available against the defendant (respondent). A variety of court orders may be issued in connection with or as part of the judgment to enforce a right, award damages or restitution, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes.
Maxims of equity are legal maxims that serve as a set of general principles or rules which are said to govern the way in which equity operates. They tend to illustrate the qualities of equity, in contrast to the common law, as a more flexible, responsive approach to the needs of the individual, inclined to take into account the parties' conduct and worthiness. They were developed by the English Court of Chancery and other courts that administer equity jurisdiction, including the law of trusts. Although the most fundamental and time honored of the maxims, listed on this page, are often referred to on their own as the 'maxims of equity' or 'the equitable maxims', it cannot be said that there is a definitive list of them. Like other kinds of legal maxims or principles, they were originally, and sometimes still are, expressed in Latin.
Estoppel is a judicial device in common law legal systems whereby a court may prevent or "estop" a person from making assertions or from going back on their word; the person so prevented is said to be "estopped". Estoppel may prevent someone from bringing a particular claim. Legal doctrines of estoppel are based in both common law and equity. Estoppel is also a concept in international law.
Copyright misuse is an equitable defence to copyright infringement in the United States based upon the doctrine of unclean hands. The misuse doctrine provides that the copyright holder engaged in abusive or improper conduct in exploiting or enforcing the copyright will be precluded from enforcing his rights against the infringer. Copyright misuse is often comparable to and draws from the older and more established doctrine of patent misuse, which bars a patentee from obtaining relief for infringement when he extends his patent rights beyond the limited monopoly conferred by the law.
Restitution and unjust enrichment is the field of law relating to gains-based recovery. In contrast with damages, restitution is a claim or remedy requiring a defendant to give up benefits wrongfully obtained. Liability for restitution is primarily governed by the "principle of unjust enrichment": A person who has been unjustly enriched at the expense of another is required to make restitution.
A declaratory judgment, also called a declaration, is the legal determination of a court that resolves legal uncertainty for the litigants. It is a form of legally binding preventive by which a party involved in an actual or possible legal matter can ask a court to conclusively rule on and affirm the rights, duties, or obligations of one or more parties in a civil dispute. The declaratory judgment is generally considered a statutory remedy and not an equitable remedy in the United States, and is thus not subject to equitable requirements, though there are analogies that can be found in the remedies granted by courts of equity. A declaratory judgment does not by itself order any action by a party, or imply damages or an injunction, although it may be accompanied by one or more other remedies.
A legal remedy, also referred to as judicial relief or a judicial remedy, is the means with which a court of law, usually in the exercise of civil law jurisdiction, enforces a right, imposes a penalty, or makes another court order to impose its will in order to compensate for the harm of a wrongful act inflicted upon an individual.
International News Service v. Associated Press, 248 U.S. 215 (1918), also known as INS v. AP or simply the INS case, is a 1918 decision of the United States Supreme Court that enunciated the misappropriation doctrine of federal intellectual property common law: a "quasi-property right" may be created against others by one's investment of effort and money in an intangible thing, such as information or a design. The doctrine is highly controversial and criticized by many legal scholars, but it has its supporters.
In pari delicto , Latin for "in equal fault ", is a legal term used to refer to two persons or entities who are equally at fault, whether the malfeasance in question is a crime or tort. The doctrine is subject to a number of exceptions, including that the plaintiff must be an active, voluntary participant in the wrongful conduct, the plaintiff's wrongdoing must be at least substantially equal to or greater than that of the defendant, the "adverse interest" exception, and the "innocent insider" exception.
Ex turpi causa non oritur actio is a legal doctrine which states that a plaintiff will be unable to pursue legal relief and damages if it arises in connection with their own tortious act. The corresponding Ex turpe causa non oritur damnum, "From a dishonourable cause, no damage arises" is a similar construction. Particularly relevant in the law of contract, tort and trusts, ex turpi causa is also known as the illegality defence, since a defendant may plead that even though, for instance, he broke a contract, conducted himself negligently or broke an equitable duty, nevertheless a claimant by reason of his own illegality cannot sue. The UK Supreme Court provided a thorough reconsideration of the doctrine in 2016 in Patel v Mirza.
Equitable remedies are judicial remedies developed by courts of equity from about the time of Henry VIII to provide more flexible responses to changing social conditions than was possible in precedent-based common law.
An adequate remedy or adequate remedy at law is part of a legal remedy which the court deems satisfactory, without recourse to an equitable remedy This consideration expresses to the court whether money should be awarded or a court order should be decreed.. Adequate remedy at law refers to the sufficient compensation for the loss or damages caused by the defendant with a proper monetary award. The court must grant the adequacy of remedy that will lead to a "meaningful hearing". Whether legal damages or equitable relief are requested depends largely on,whether or not the remedy can be valued. Both two elements, compensation and the meaningfulness of hearing, provide a proper way to have an adequate remedy. The word "meaningfulness" of hearing in the law process is the assumption that the defendant compensated must be meaningful for the injured party where the defendant made a fully covered compensation for all the losses. Hence, the hearing in which cannot give any right amount of compensation award or settlement is not "meaningful", and the unavailability of the compensation will lead to an inadequate remedy. The adequate remedy at law is the legal remedies by meaning it is satisfactory compensation by way of monetary damages without granting equitable remedies.

Cayuga Indian Nation of New York v. Pataki, 413 F.3d 266, is an important precedent in the United States Court of Appeals for the Second Circuit for the litigation of aboriginal title in the United States. Applying the U.S. Supreme Court's recent ruling in City of Sherrill v. Oneida Indian Nation of New York (2005), a divided panel held that the equitable doctrine of laches bars all tribal land claims sounding in ejectment or trespass, for both tribal plaintiffs and the federal government as plaintiff-intervenor.
A patent holder in Canada has the exclusive right, privilege and liberty to making, constructing, using and selling the invention for the term of the patent, from the time the patent is granted. Any person who does any of these acts in relation to an invention without permission of the patent owner is liable for patent infringement.
Morton Salt Co. v. G.S. Suppiger Co., 314 U.S. 488 (1942), is a patent misuse decision of the United States Supreme Court. It was the first case in which the Court expressly labeled as "misuse" the Motion Picture Patent/Carbice tie-in defense to a charge of patent infringement and created the present blanket remedy in infringement cases of unenforceability of the misused patent. The decision re-emphasized that misuse can be found without finding an antitrust violation.
Motion Picture Patents Co. v. Universal Film Mfg. Co., 243 U.S. 502 (1917), is United States Supreme Court decision that is notable as an early example of the patent misuse doctrine. It held that, because a patent grant is limited to the invention described in the claims of the patent, the patent law does not empower the patent owner, by notices attached to the patented article, to extend the scope of the patent monopoly by restricting the use of the patented article to materials necessary for their operation but forming no part of the patented invention, or to place downstream restrictions on the articles making them subject to conditions as to use. The decision overruled The Button-Fastener Case, and Henry v. A.B. Dick Co., which had held such restrictive notices effective and enforceable.
