Patent Landscape Report on Biochips

Patent Landscape Report on Biochips

This report categorizes and graphically analyzes biochips from various perspectives such as the fabrication techniques, methods involved, biochip types and applications and highlights the key companies involved.

Publication Trend

Innovation around biochips and resulting patent publications started to show up from 1986 with a spike in 2002.

It’s clear the current activity around these technologies is likely to continue seeing more innovation in the near future.

Top Companies

The top companies in biochips are:

Research activity around the world

The table below ranks top priority countries and helps provide an indication of where innovation in this area is originating. It shows perfect indication of where innovation is taking place. It can be seen China has 1201 filings (INPADOC Families) followed by US and Korea with 629 and 565 filings respectively. The strength of the colouring represents the proportion of patent publications.

Company activity across Applications

The chart below shows research activity of companies across different applications

• Merck leads the research around Biomarkers and Organic Semiconductors
• Rosetta Genomics leads the research for diagnosis of cancer using biochips, it also leads the record count for Hybridization
• Nucleotides and Gene Diagnosis are the application areas wherein most of the companies are present

Biochip – Types vs Methods

In the map, different types and methods are connected through links whose thickness and color intensity is directly proportional to the number of records relating them. The number (in red) next to each line represents the number of records present in the respective category. It can be that Gene Expression and Electrophoresis are the methods where DNA chips are used the most.

Also, ELISA followed by Gene Expression is more often used by Protein Chip for diagnostic purposes. Similarly, Thin Layer Chromatography and Magnetism are exclusive to Protein Chip and DNA Chip.

Technology Landscape for Methods

The contour map below represents key concepts for different companies across various methods where biochips are used.

Clusters for Internal Radioimmunoassay, Immunohistochemical and Immunofluorescence are close to each other as there is high degree of relevance between the records present in those types of methods. The patents represented by dots were coloured by company.
