From the news:
The 260 Patent is intended to protect the use of the Hemopurifier® in the United States to treat patients that have a reduced COVID-19 viral load but exhibit Long COVID symptoms for more than 12 weeks post infection. The 260 Patent additionally protects the treatment of patients experiencing Long COVID symptoms by the removal of circulating COVID-19 spike protein.
The 453 Patent is intended to protect the use of the Hemopurifier® for the treatment of patients that lack circulating COVID-19 viral particles but exhibit COVID-19-associated CAC.
The 260 Patent was granted an additional 385 days of patent term due to patent term adjustment and will expire in 2042. The 453 Patent will expire in 2041.
"We believe securing these patents expands and strengthens our intellectual property portfolio in areas of significant unmet medical need,” said James Frakes, CEO and CFO of Aethlon. “While the Hemopurifier® remains in the research and development stage relating to Long COVID, these protections position us well as we continue advancing potential future applications. Our goal is to build a strong foundation of innovation that could one day translate into meaningful treatment options for patients."
The Aethlon Hemopurifier® is an investigational medical device designed to remove enveloped viruses, fragments of viruses, and tumor-derived extracellular vesicles (EVs) from circulation. It is used extra-corporeally with a blood pump and combines plasma separation, size exclusion, and affinity binding using a plant lectin resin that targets mannose-rich surfaces found on EVs and viral proteins. EVs released by solid tumors are believed to play a role in metastasis and the resistance to immunotherapies and chemotherapy. Removal of enveloped viruses, fragments of viruses, and extracellular vesicles has been demonstrated in both in vitro studies and in human patients.
The Hemopurifier® holds a US Food and Drug Breakthrough Device Designation for:
The treatment of individuals with advanced or metastatic cancer unresponsive to or intolerant of standard-of-care therapy; and the treatment of life-threatening viruses not addressed with approved therapies.
In addition to this patent news, Aethlon has the following patents issued and multiple patents pending in the US and Internationally:

This approval strengthens Inspira’s intellectual property portfolio and reinforces the Company’s technological leadership in the field of advanced extracorporeal life support.
Dagi Ben-Noon, Chief Executive Officer of Inspira Technologies, stated: "This patent has profound business implications for Inspira and for our ability to dominate a market with a potential size of $20 billion. We are creating a new therapeutic category for conscious, spontaneously breathing patients. Protecting our intellectual property is a critical pillar of our growth strategy, and this patent approval provides us with a distinct competitive advantage. While our ART100 system is already generating commercial momentum, this move fortifies our future and gives us the clear runway needed to translate our technological leadership into long-term value for our shareholders, and a new standard of care for patients worldwide."
The newly received patent provides protection at least until the year 2043, covering key claims related to the ART500’s functionality, design, and clinical applications. Inspira is pursuing additional patents in major jurisdictions worldwide to expand its intellectual property coverage.
