Which scenarios would require filing a new application data sheet for updates?

The requirement to file a new application data sheet (ADS) is crucial in certain scenarios, particularly when it comes to changes that have substantial relevance to the patent application. Changing the inventorship is one of those key scenarios. When inventorship changes, it can significantly impact the ownership rights associated with the patent application. This can arise due to a variety of reasons, such as an addition or removal of inventors based on their contributions to the invention. Therefore, to maintain the integrity and clarity of the application, it is necessary to file an updated ADS reflecting the accurate inventorship.

Claiming priority, which pertains to establishing earlier filing dates based on previous applications, also requires an updated ADS. This is because the original details that were submitted may no longer be sufficient to represent the current claim to priority accurately.

On the other hand, while changing an address is administratively important, it typically does not necessitate an entirely new ADS since it is not as fundamental as changes in inventorship or priority claims. Routine updates like address changes can often be managed without requiring a complete filing of a new ADS.

Thus, the choice emphasizing both the correction of inventorship and the claiming of priority as reasons for requiring a new ADS reflects the fundamental changes that must be documented
