After a slow six month ramp-up, the number of petitions challenging patents under the new system has grown significantly, reaching nearly 200 new filings a month. It takes 18 months for a patent challenge to make its way through the PTAB, and we are now finally seeing the effects of the influx. Now, with 75% of all trials resulting in every challenged patent claim being invalidated, it’s clear that the PTAB will have a very broad reach in patent litigation.
The intellectually hard work of software isn't the idea. It's almost entirely within the coding.
Good ideas usually come in a flash, so they appear to be "cheap." However, they are also usually the result of trial and error over and over again and being deeply entrenched in the field.

The patent appears to cover a method of landing a rocket on a floating platform at sea. In their papers, SpaceX says that "by 2009, the earliest possibly priority date listed on the face of the patent, the basic concepts of 'rocket science' were well known and widely understood. The “rocket science” claimed in the ‘321 patent was, at best, 'old hat[.]'" Blue Origin has approximately three months to file a preliminary response to the challenge.

1. An illumination device, comprising:
a light source, comprising an array of a plurality of light emitting devices;
an illumination uniformizing means disposed in front of the light source to uniformize a light emitted from the light source, the illumination uniformizing means comprising:
an incident plane, the light emitted from the light emitting device array is incident therefrom;
a bottom plane, comprising a scattering pattern thereon;
a projection plane opposite to the bottom plane, wherein:
the light incident from the incident plane being scattered by the scattering pattern, while the light incident from the incident plane being totally reflected between positions of the bottom plane other than the scattering pattern and the projection plane; and
a reflective side plane opposite to the incident plane, wherein the scattering pattern is gradually condensed from the incident plane towards the reflective side plane; and
a polarization converter, disposed between the illumination uniformizing means and a light valve, to polarize the light from the illumination uniformizing means into a polarized light.
