MediSieve is Granted US Patent
The patent for MediSieve’s magnetic blood filter has now been granted in the United States.
LONDON – June 13, 2019 – Medical device company MediSieve, which has developed the concept of magnetic blood filtration to remove disease-causing agents from the blood, has been awarded a patent for its product in America.
The patent for MediSieve’s magnetic blood filter has now been granted in the United States. With patent number US10265457B2, it’s titled ‘Magnetic filter apparatus and method’ and covers the company’s filter, magnet and system for extracting magnetic components such as malaria-infected cells from the bloodstream.
The patent has also been filed under PCT and is pending in Europe, Canada, Japan, China, India, Brazil and Australia.
Founder of MediSieve Dr George Frodsham, said: “This is an important step – there’s a big difference between filing a patent and having it granted. Having patent protection is important to protect our technology and market share.
“The US is still the world’s biggest healthcare market, and this cements our position as the global leader in magnetic blood filtration. It puts us in a strong position against any potential competitors, and is a milestone validating the innovative nature of our unique technology. The next step is for the other patents to come through, and we expect this to start happening soon.”
The patent was granted in late April, and expires in 2037. It was originally filed in September 2016 through patent attorney Tom Turano at Boston-based K&L Gates.
MediSieve’s magnetic blood filter removes malaria infected red blood cells by passing blood through a strong magnetic filter which captures the infected cells by exploiting their naturally occurring magnetic properties. The rest of the blood is then returned to the infected patient. The same device can be used to capture other magnetic components, namely MediSieve’s magnetic particles designed to bind to specific targets in blood to enable their removal.
The company aims to launch their malaria treatment in 2021. The first clinical trials are planned for later in 2019, before Phase two trials take place in malarial areas.
The patent news comes after MediSieve announced that it has been awarded two grants from Innovate UK, worth some £1.56m in all.
MediSieve was established in 2015 as an independent company and has its origins in University College London. The company is based in London’s White City, at the Imperial College Translation and Innovation Hub.
About Magnetic Blood Filtration
MediSieve's Magnetic Blood Filtration Platform is intended to enable the rapid and specific depletion of specific agents from the bloodstream of patients. The extracorporeal therapy uses therapeutic Magnetic Beads that are designed to bind specifically to the clinical target. The Beads are introduced into the extracorporeal circuit during the therapy, mixing with the patient’s blood and binding to the clinical targets. The Delivery Platform captures all the Magnetic Beads and bound targets, preventing their return to the patient.
About MediSieve
MediSieve is a London-based BioTech start-up that has developed Magnetic Blood Filtration, a revolutionary platform therapy that enables the physical removal of specific substances from the bloodstream of patients. It can be used (1) as a direct treatment, (2) to increase the safety and efficacy of other therapies, or (3) to enable personalised medicine. The company is a spin-off from University College London and is developing its products at the White City Innovation District in West London. MediSieve is actively seeking investment and partnerships.
