- Nonexclusive License
- A grant of rights that allows the licensee to use the invention while the licensor retains the ability to grant identical rights to any number of other parties.
- Licensor
- The party that owns the patent or invention rights and grants permission to another party to use them under defined conditions.
- Licensee
- The party receiving the right to use, make, sell, or otherwise exploit the licensed invention within the scope defined by the agreement.
- Field of Use
- A contractual restriction limiting the licensee's rights to a specific industry, application, product category, or territory — allowing the licensor to grant different fields to different licensees.
- Royalty
- Ongoing compensation paid by the licensee to the licensor, typically calculated as a percentage of net sales or a fixed fee per unit manufactured or sold.
- Sublicense
- A right, if granted by the licensor, for the licensee to extend some or all of its licensed rights to a third party — creating a three-party chain of IP rights.
- Patent Prosecution
- The administrative and legal process of obtaining and maintaining a patent, including responding to patent office actions, paying maintenance fees, and defending against invalidity challenges.
- Infringement
- Unauthorized use, manufacture, or sale of a patented invention by a party who has not been granted a license, potentially entitling the patent holder to damages and injunctive relief.
- Milestone Payment
- A one-time lump-sum fee triggered by the licensee reaching a defined commercial event — such as first product sale, regulatory approval, or a revenue threshold.
- Reversion Clause
- A contractual provision that returns rights to the licensor if the licensee fails to meet minimum performance obligations, such as annual royalty minimums or commercialization deadlines.
- Grant-Back
- A clause requiring the licensee to license back to the licensor any improvements or derivative inventions the licensee develops based on the original licensed technology.
- Reach-Through Royalty
- A royalty on products or revenues downstream of the licensed technology — common in research tools licensing, where the licensor claims a share of products developed using the tool.
