Historically, tumultuous times offer some of the best opportunities to buy stocks, and the market's recent mess surely qualifies. Many investors have written off the tech sector, but there's still plenty who think that intellectual property licensor Rambus (NASDAQ:RMBS) shouldn't get thrown out with the tech bathwater.

In our Motley Fool CAPS community, nearly 84% of the 502 investors rating the company are bullish, so there's no shortage of reasons why Rambus will thrive. I've highlighted three below.

But here at The Motley Fool, we're all for looking at both the good and bad sides of an investment. Once you're done with this article, you can read the case against Rambus, weigh in with your own comments below, or rate Rambus yourself in CAPS.

1. High-margin royalties
Similar to ARM Holdings and Qualcomm (NASDAQ:QCOM), Rambus owns a litany of patents that help it bring in licensing revenue from many top-tier customers such as AMD (NYSE:AMD), Intel (NASDAQ:INTC), Panasonic, and IBM (NYSE:IBM). The intellectual-property-licensing model is very profitable when it works, and many investors think the future demand for Rambus' technologies will lead to significant increases in high-margin royalty revenue.

2. Growing markets
Companies like Micron Technology (NYSE:MU) are seeing some relief from the oversupply and weak demand that has recently characterized the semiconductor market. And Rambus has enjoyed an uptick in demand across its focus markets -- industry reports show improving PC and LCD TV shipments, and the company expects the recent strength in sales of Sony's (NYSE:SNE) PlayStation 3 to continue.

3. Litigation windfalls
Current Rambus investors already know that coming out on the wrong end of a legal tussle can bite you hard. But some investors argue that current license agreements and court decisions in Rambus' favor have laid a strong precedent, boding well for some big legal wins eventually. Rambus is currently keeping its legal team very busy with multiple litigations, some of which have the potential to be very lucrative, and investors see numerous ways in which the company's patents can be milked for all they're worth.
