Circulating DNA/RNA Patent Landscape Report 2021: Oppositions and Litigations, Key Patent Analysis, Patent Database

·6-min read

Dublin, July 05, 2021 (GLOBE NEWSWIRE) -- The "Circulating DNA/RNA Patent Landscape 2021" report has been added to ResearchAndMarkets.com's offering.

Circulating nucleic acids tests, an essential step in prognosis and personalized treatment

In clinical practice today, one of the most eagerly awaited technologies is the liquid biopsy, and, more specifically, the analysis of circulating DNA, which is a safer alternative to solid biopsy.

It is a useful and essential element for achieving personalized medicine. It is also a minimally invasive approach for diagnosing or prognosing a disease through markers (e.g. mutations) in body fluids such as blood, urine, saliva, cerebrospinal fluid or pleural fluid. Circulating DNA/RNA analysis is not restricted to oncology, though the research and needs in this area are immense and eagerly awaited.

This technology is also applicable to prenatal diagnostics, cardiovascular and nervous system diseases or transplantation. In addition, the development of technologies to intercept and analyze these circulating nucleic acids steeply increased in the last 10 years, as did the number of companies supplying them (e.g. Grail, Guardant Health, Roche, Illumina).

In the cancer area, great progress has been made in the last 5 years, since 3 medical devices have arrived on the market and have been FDA approved: the cobas EGFR Mutation Test and FoundationOne Liquid CDx by Roche; and the Guardant360 CDx by Guardant Health.

The FDA has also granted three Breakthrough Device Designations for a Natera test. At the same time, the number of clinical studies observing circulating nucleic acids continues to increase, reflecting the growing interest in this topic as well as the economic stakes for companies. Despite this, multiple issues are delaying the widespread incorporation of ctDNA into routine patient care.

Future focus should be on establishing optimal techniques for sample collection, cfDNA isolation and analysis. In addition, further studies are required to better understand the biological characteristics of cfDNA.

In terms of intellectual property (IP), circulating DNA/RNA is of interest to big companies and start-ups alike, and it is crucial to understand the IP position and strategy of these different players. Indeed, significant numbers of litigations and oppositions have been filed recently, showing the strategic role of IP in this area. Such knowledge can help detect business risks and opportunities, anticipate emerging technologies, and enable strategic decisions to strengthen one's market position.

Until 2009, there was a latent period, although highly specialized companies in the field started to emerge, such as CLS Therapeutics, Sequenom (acquired by Integrated Genetics) and OncoMEDx. Some academics also started to take an interest in this field of research, such as American universities (Pennsylvania and John Hopkins) and Chinese universities. Since 2010, an acceleration in patenting activity has been observed, with the arrival of big newcomers such as Roche, Natera, Illumina and BGI.

Oppositions and litigations

There is a significant number of EP oppositions (>30) and US litigations for patent infringement (>20), which reflects the strategic issues of circulating DNA/RNA for companies. Most of the proceedings are recent, filed in the past 3 years, and are still pending.
Identifying the companies that have recently emerged in the IP landscape

Among the players owning patent families related to circulating DNA/RNA, over 100 newcomers were identified. These companies are either established companies or start-up firms developing their first methods and/or products in the cell-free DNA/RNA field. These technologies are mainly related to cancer or prenatal diagnostics. Numerous IP newcomers are based in the US and in Asia while some are based in Europe. It is possible that one of these innovative companies could become one of the next healthcare unicorns that the big corporations will be tempted to acquire.

Key patent analysis

This IP study includes a selection and description of key patents. The key patent analysis includes the legal status of the family for each of the main territories, the number of received citations, the review of the main claim(s), the description of interesting features about the innovation disclosures and relevant figures illustrating how the innovation works. The description also contains information about litigation over the patent family in the USA.

Useful Excel patent database

Moreover, the report also includes an Excel database with the >2,240 patents analyzed in this study. This useful patent database allows for multi-criteria searches and includes patent publication numbers, hyperlinks to the original documents, priority dates, titles, abstracts, patent assignees, each patent's current legal status and segmentation.
