The company said that it has actively sought three patents in forty countries around the world relating to its system for biological control of pathogens in crops and delivery system using bees.

The notice of approval has been received from the US Patent and Trademark Office on the two following applications:

• Application 14/483,345 relates to a formulation comprising a particulate calcium silicate and can contain clonostachys rosea for treating plants (Vectorite). BVT's Vectorite is a proprietary mixture of products that allows the inoculant to get attached to a bee's hairy legs and body as it walks through the tray on their way out of the hive. The Vectorite allows for delivery of BVT inoculums either individually or together with other bio-controls and crop controls;
• Application 14/110,323 relates to specialist apparatus for the treatment of plants (inoculum dispenser and tray). The BVT inoculum dispenser system is incorporated into the lid of commercial bumblebee hives. In the dispenser is a removable tray that contains, in powder form, the inoculant crop control and a mixture of products (Vectorite) that allows the bees to effectively pick up the product on their way out of the hive.

The third application, which relates to an active ingredient used in the BVT system, remains within the official process pending approval. This application was filed at a later date than the other two now approved.

BVT CEO, Michael Collinson, said, "Gaining approval on patent applications within the US is notoriously difficult and securing these represents another major step for BVT in the implementation of its global growth strategy. We will continue our pursuit of full patents in approximately forty additional countries around the world. The delivery system is now protected by these patents and the system is being commercialised with other bio controls."
