WEB has applied for a patent on the method of wavelet angiography: There is a patent submission USPTO 62187631 Wavelet Reconstruction of Moving Brain Pulse on the wavelet angiography method employed to produce the data that is then subjected to further analysis in this paper. There are no declarations related to employment, consultancy, products in development, etc. This does not alter my adherence to PLOS ONE policies on sharing data and materials.
