A more thorough explanation:

Definition: Interference refers to the legal process of resolving disputes between two parties who claim the same intellectual property rights. This can occur when two patent applications are filed for the same invention or when two trademarks are too similar.

Example: Company A files a patent application for a new type of smartphone. A few months later, Company B files a similar patent application for the same type of smartphone. This creates an interference, and the two companies must go through a legal process to determine who has the right to the patent.

Example: Another example of interference is when two companies have similar trademarks. For instance, if Company A has a trademark for "Apple" for their line of computers, and Company B tries to trademark "Apples" for their line of phones, this could create an interference.

These examples illustrate how interference can arise when two parties claim the same intellectual property rights. The legal process of interference proceedings is used to resolve these disputes and determine who has the rightful claim to the intellectual property.
