just info for RotoGro vs RavenQuest and Robertsonthis is just info around the infringement lawsuit against Ravenquest Biomed by RotoGro
if RavenQuest is seeking to invalidate RotoGro's patent then there will be early info available on the Canadian patent site ...specifically here
https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2908184/summary.html?query=Roto-gro&type=advanced_search I find it useful to follow any filings as they will give an indication of what direction things are heading. Currently it isn't showing any filing contesting the patent though RavenQuest has indicated that that was the approach they were taking. Also looking to any cout docs but the Canadian Fed Courts aren't showing any on this that I can find...US courts are far easier to get all filings.
this is RotoGro's take on things
https://www.rotogro.com/2019/11/rotogro-files-patent-statement-of-claim/ this is the troublesome part in that RavenQuest and Robertson did the infringement knowingly and now are relying on invalidation the patent...not a great stategy in my opinion.
the only reason I'm posting this as they are handy for info and I was looking at this company for investing but decided for me that this infringement is core to their method of growing and could be not so good. There are solution but it would involve some bargaining to appease RotoGro as I feel things are well in their favor. Anyway, best of luck
