Hosting server hiccup, earthquake, updating. Long list of possibilities.
You won't find anything until USPTO publishes it (granted patents or applications), unless it's from the company. Seems about a 6 month ordeal from application date to publish date.
Use David T. Markus to find current patents. The only thing I haven't tried is a patent lawyers name they might be using.
Otherwise, I think the effort is fruitless now, as the time to publish from the app. date is around 6 months, if granted patent.
I believe they are there, just not available for public eyes.
IMO
