Open the CIPO recordAbstract From the Canadian patent
NMR spectroscopy data recovery methods and apparatus for improving the quality of an NMR spectrum are disclosed. The NMR spectrum is improved by acquiring more than the half spin-echo data signal(301) and using an iterative numerical method to reconstruct the missing data points of the corresponding full symmetrical spin-echo data signal. The method includes filtering the initial data signal to extract a low-resolution phase term (302). The low-resolution phase term is used to form a phase-constrained initial data signal which is , Fourier-transformed to obtain a reconstructed data signal (303). The reconstructed data signal is modified to include the original spin-echo signal data …

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents, and the Claude kit works from them.
Why it's free to use
- Filed April 1, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 1, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
