Diagnostics & Biosensors

The swift diagnosis and treatment of a disease depends on the development of products and methods that allow for identification of defective disease causing components, the presence of the disease itself and an indication of key molecules which could form an effective treatment.

Biosensors act to identify key molecules or elements, in a particular medium, for example soil, water, chemical mixtures or fluids. Sensors have typically been the preserve of Chemists, but in recent years, sensors using immobilised biological materials such as enzymes or antibodies have become more common.

Within both areas of diagnosis and biosensors, imaging technologies such as fluorescence, phosphorescence and luminescence play a big part in the display of results in a visual format for ease of analysis.

Appleyard Lees has significant experience in helping clients secure protection for medical devices in the field of diagnosis, including domestic pregnancy/menopause/STI kits or commercial diabetes/ MRSA/arthritis kits, drug screening tools, and microarrays. We have also worked with many UK and US universities on heavy metal detection and mineral level indication using enzymes, the fluorophore tagging of drugs or receptors in the human body and fundamental equipment such as mass spectrometers. The law in the UK and Europe currently precludes patent protection for methods of diagnosis of the human or animal body. This has resulted in numerous decisions from the courts. That is not to say that you can’t get valid patent protection for certain diagnostic methods and Appleyard Lees has expertise in minimising the impact of these exclusions so as to secure maximum patent protection for your invention.
