   The Patent Act of 1790:

   • The United States issued its first patent under the Patent Act of 1790. The act granted inventors the exclusive right to their inventions for a term of 14 years. It covered machines, manufacturing processes, and compositions of matter.

2. Patent Act of 1836:

   • The Patent Act of 1836 established the United States Patent Office (now the United States Patent and Trademark Office or USPTO) and introduced significant revisions to patent law. It extended the patent term to 21 years and implemented a formal examination process.

3. The Bayh-Dole Act of 1980:

   • The Bayh-Dole Act allowed universities, small businesses, and non-profit institutions to retain ownership of inventions developed with federal funding. It facilitated the commercialization of federally funded research and encouraged collaboration between academia and industry.

4. America Invents Act (AIA) of 2011:

   • The AIA introduced substantial changes to U.S. patent law, transitioning from a “first-to-invent” to a “first-inventor-to-file” system. It aimed to streamline the patent application process and harmonize it with international standards.

5. Diamond v. Chakrabarty (1980):

   • In this landmark Supreme Court case, the Court held that living organisms, specifically a genetically modified microorganism, could be patented. This decision expanded the scope of patentable subject matter to include certain forms of life.

6. Mayo v. Prometheus (2012) and Alice v. CLS Bank (2014):

   • These Supreme Court decisions clarified the boundaries of patent eligibility for certain types of inventions, particularly in the fields of biotechnology and software. The Court emphasized the importance of not granting patents on laws of nature, natural phenomena, or abstract ideas.

7. Patent Cooperation Treaty (PCT) and International Patent Protection:

   • The United States, along with many other countries, is a party to the PCT, which facilitates the filing of patent applications internationally. This enables inventors to seek patent protection in multiple countries through a single application.

8. Inter Partes Review (IPR) Proceedings:

   • The AIA introduced IPR proceedings, allowing third parties to challenge the validity of issued patents before the Patent Trial and Appeal Board (PTAB). IPR has become an important mechanism for resolving patent disputes.

9. Ongoing Efforts for Patent Reform:

   • Policymakers continue to explore and propose reforms to address issues such as patent litigation abuse, patent quality, and the role of patents in emerging fields like biotechnology and artificial intelligence.

The history of U.S. patent law reflects a balance between fostering innovation and ensuring fair access to inventions. Legal developments have responded to technological advancements and global trends, shaping a legal framework that continues to evolve in the face of new challenges and opportunities in the field of intellectual property.
