Rule against Vitiation of a Claim Element [Patent]
Understanding the Rule against Vitiation of a Claim Element [Patent]
Definition & Meaning
The rule against vitiation of a claim element is a principle in patent law. It states that under the doctrine of equivalents, a patent cannot be infringed if even one element of the patent claim, or its equivalent, is absent from the accused product or process. This rule serves to limit the application of the doctrine of equivalents to individual elements of a claim, rather than allowing it to apply to the claim as a whole. It is also referred to as the all-limitations rule or all elements rule.

Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: A patent for a specific type of engine design includes a claim for a unique fuel injector. If a competitor creates an engine that lacks this fuel injector, they cannot be found liable for infringement under the rule against vitiation.
Example 2: A hypothetical example would be a patent for a smartphone that claims a specific camera feature. If another smartphone lacks that feature, it cannot be considered an infringement, even if it has similar capabilities.
