Key Differences
The "filing date" is the specific date on which a document, often a legal or patent application, is officially submitted and recorded. In contrast, the "priority date" in immigration is the date when the U.S. Citizenship and Immigration Services (USCIS) receives your petition, which determines your place in the waiting line for a visa.
While the "filing date" marks the official recognition and record of a document, establishing a timeline for potential future disputes or claims, the "priority date" is crucial for applicants awaiting visa availability, especially in categories subject to annual limits.
The "filing date" is universally acknowledged as the commencement of the legal timeline for the document filed, be it a patent, lawsuit, or another official submission. However, the "priority date" serves as a benchmark in immigration, ensuring fairness by processing applications in the order they are received.
For inventors, the "filing date" of a patent application is pivotal in establishing their claim to the invention, whereas the "priority date" is less common in this context, often referring to the filing date of an earlier, related application for the purpose of establishing precedence.
In summary, the "filing date" refers to the official submission date of various legal documents, while the "priority date" is predominantly used in immigration contexts to establish an applicant's place in the often lengthy visa queue.
