Patents do exist on popular IP cores, but in general standards compliant Verilog libraries are just vendor specific IP products. Thus, the copyright, NDA, and license agreements already keep the IP fairly locked down. For example, figuring out dram timing and DDR bus control yourself is nontrivial.

Some groups have attempted open IP cores, and made some progress:

However, the effort involved in getting standards compliant ASIC built puts folks in a Fabless manufacturing sector. Most firms that survive, will choose to stay with a generic FPGA option to avoid custom silicon unless absolutely necessary.

Patents are often useless/vague in many places, but on occasion may prevent platform decay for a few years. One can be sure a unique/new design will not go to fab unless such protection is in place. =3

It seems like the fab companies like TSMC/Samsung/GF/Intel are missing an opportunity here. Commoditize your complement:

Publish the software that does this for free so that more customers come to you instead of using FPGAs or just not making the attempt. Make it easier to design new chips so that more people do it and you get more customers.

When it comes to hardware, the OSS model stops making economic sense.

People have tried, but helping other competitors for free rapidly decays the market. =3

Rule #23: Don't compete to be at the bottom, as you just might actually win.

The point isn't to help your competitors, it's to help your customers. Qualcomm or Apple doesn't have the incentive to help their competitors design chips, but TSMC or Samsung does have the incentive to help Qualcomm's competitors design chips, because then there are more companies making chips and the fab gets more business and prevents any one of their customers from getting too much leverage over them.

		Samsung actually had a technological lead in many areas, and it translated into real revenue. They are a business, and exist to provide utility to consumers in exchange for investor profit: https://www.youtube.com/watch?v=KCWDzWG1BcI Many incentives to push technology forwards are high-risk/expensive investments, and expecting the public/customers to willingly help pay that cost is naive: https://www.youtube.com/watch?v=cru2bkqwSYk I assure you academic funding does not cover such large costs, government grants are only a fraction of expected taxes in late stage Technology Readiness Levels, and competitor/cloner fractured markets erode fiscal returns needed to pay for the total incurred project cost. Apple makes minimal utility products, but relies on intangible branding to maintain perceived value. Thus, only Apple could get away with selling zero chip designer handbags, and would still make absurd revenue (not a real product yet.) Steve Jobs observed very early, that selling raw motherboards was a low margin business. Which it was why the company shifted into consumer products. For almost every other brand, consumers have shown they prefer the near material cost in opportunistic China/India factories, and thus simply ignore most firms products that include 10 years of R&D costs to pay back the investors. There are many shelved technologies that will never see a Patent or the public markets. This is because the conditions are not ready for advanced products yet, and competitors irrationally nurture the lowest value volume market sectors. Thus, everyone gets a 15% value boost at regular intervals, and people remain excited about 3 decade old technology. Qualcomm cellular chip product lines essentially lived off iPhone sales. Like any loyal dog, they will unlikely bite the hand that feeds them... Rule #3: popularity is not an indication of utility. Have a wonderful day =3
