A request appears to be about patents related to “patente a 17 anni da quando” (patent term of 17 years from grant). Here’s what’s relevant: in many jurisdictions, patent term lengths differ; historically some U.S. patents granted before June 8, 1995 had a 17-year maximum from grant, but modern U.S. patents generally have a 20-year term from earliest non-provisional filing date. The exact term for a specific patent depends on its grant date, filing date, and any term adjustments or extensions. Subtasks addressed
- Determine typical patent term regimes (historical 17-year rule vs. 20-year from filing) and how they apply in practice.
- Note special cases like term adjustments, extensions, and patent-family variations.
Key concepts
- Historical U.S. rule (pre-1995): patent term often 17 years from grant date for many older patents.
- Modern U.S. rule (post-1995): patent term generally 20 years from earliest effective filing date, with possible term adjustments or extensions (e.g., for FDA regulatory data, or for certain technology families).
- Other jurisdictions (EU, JP, etc.) have their own term structures, typically 20 years from filing date without the 17-year grant-based term.
Practical guidance
- To determine a specific patent’s term, you must know:
- The grant date and the filing date (or priority date) of the patent.
- Whether the patent is subject to any term adjustments or extensions.
- Jurisdiction-specific rules if the patent is outside the U.S.
- If you provide a specific patent number (e.g., USXXXXXXB2) or the jurisdiction, the precise term can be calculated.
Direct answer
- The phrase “patente a 17 anni da quando” translates to asking about patents with a 17-year term from grant date. In practice, this term applies to older U.S. patents granted before the current 20-year-from-filing rule, but most post-1995 U.S. patents use a 20-year-from-filing term, with possible term adjustments. For a particular patent, you must check its grant date, filing date, and any term adjustments to compute the exact expiration. If a specific patent number or jurisdiction is provided, the exact expiration date can be looked up precisely.
