Chemical, Biotech and Pharmaceutical Patents

What constitutes a chemical patent? Claims in chemical patents may cover the composition of matter (how a substance is used), a product yielded by a process, a particular process, or a novel compound. One of the earliest patented chemical processes and is in fact the first US patent was awarded to Samuel Hopkins in 1790 for his process to produce potash.

Biotechnology involves harnessing biological systems, substances and processes to improve daily life. Some of these systems have been utilised for centuries before the modern patent, such as the use of yeast in brewing alcohol; biotech patents are usually awarded to the novel use of these existing, known systems to yield a new outcome. One of the earliest and most notable patents awarded in the biotech field was given to Louis Pasteur, who developed a way to heat-treat milk and several fruit juices to eliminate pathogens and extend their shelf life.

Pharmaceuticals present features of both chemical and biotechnology innovations, as drugs can originate from new approaches to extract naturally-occurring substances or be a totally novel molecule synthesised in one’s laboratory. For example, multiple anti-cancer drugs have been synthesised based on the human genetic sequence.
