Examples of Arabidopsis patents

Granted patents on genes from Arabidopsis

One of the characteristics of bulk sequence claims in plants is that they are almost always in the form of patent applications.  The applicants strategy in claiming bulk sequences is often to establish an early priority date and to later obtain granted patents on individual genes or small groups of genes derived from the initial applications.  Hence , to this point, we have considered only patent applicatons.  Whilst these applications have the potential to influence those working in dicot biotechnology, they are not granted patents.

Transcription Factors

In this section we will look more closely at examples of patents granted on cliams to Arabidopsis Transcription Factors (TFs).

This group was chosen because it includes patents granted to Mendel Biotechnology Inc., who have made application claims for bulk sequences from Arabidopsis. Since the applications are to transcription factors from Arabidopsis, they may also cover homologous sequences from other dicots.  Thus analysis of granted patents for TFs offers the opportunity to analyse an important group of genes and also the ultimate patent claims that may evolve from bulk sequence claims.

Search Strategy

The patents for Arabidopsis Transcription Factors discussed in this section were identified using the following search strategy.

Search details
Date of search 30 06 2006
Database searched Patent Lens, accessible at www.patentlens.net
Type of search Structured Search
Collections searched US-A, WO-A, US-B, EP-B, AU-B (add link to “Documents in  Collection” which will take you to a web page that describes the extent of the collection.)
Search terms (Arabidopsis AND thaliana) AND ((SEQ AND ID) in claims) AND (transcription AND factor)
Results 2,509
Comments Of the 2,509 results identified using these search terms, only the top 100 results (based on relevance score) were considered. The content of their titles, abstracts, and claims were used to identify granted patents on Arabidopsis Transcription Factors.  This procedure was in no way exhaustive, and because of the large number of transcription factors in Arabidopsis and their possible value in modifying plant phenotypes it is very likely that many TF patents were not considered in this analysis. The TF patents discussed below are representative of this group of genes from Arabidopsis.
