Deposit of biological material and the differing national laws

For patent applications in the biotechnology area, a biological material is sometimes essential for carrying out the invention. The biological material can be any material capable of reproducing itself or being reproduced in a biological system, including bacteria, fungi, algae, eukaryotic cells, cell lines, hybridomas, plasmids, viruses, and plant seeds. If the biological material cannot […]

Breakthrough in Protein Structure Prediction

Knowing the three-dimensional structure of a particular protein is critical in determining its function and has implications for everything from treating human disease to herbicide resistant plants. Researchers currently use experimental techniques such as x-ray crystallography, nuclear magnetic resonance, or cryo-electron microscopy to establish the structure. However, these techniques are time consuming and can take […]

New Grape Varieties – Raisin Awareness of Plant Patents

You may have noticed more options for grapes at your local grocery store in recent years. In addition to the typical red, black, and green grapes that have always been available, there are now unusual shapes and unique flavors including those grapes that that taste like cotton candy! But have you thought about how these […]
