TechDirt recently published a provocative article, titled “Meet the Patent Thicket: Who’s suing Who for Smart phone patents.”
I have one observation to make. Though this is an interesting article, the author gave it a misleading title. That is the point of this post.
The article should be called “Divided technical leadership and lawsuits in smartphones.” I have to explain two things. Why the article says something about divided technical leadership, and why it does not say something about patent thickets.
The primary illustration from the article is reproduced on the left (under a cc license, attributing authorship to TechDirt). This gives you a good feel for the article’s main fact: many companies are suing each other. Most of these firms are large. A few firms are not. Many of these suits concern patents for smart phones.
The article offers opinions about a few of these suits, and which ones seem to be most important. It also has plenty to say about the lawsuits taking place right now, and why other recent reports are inaccurate. It is a good read, and I recommend it.
The article actually has little to say about patent thickets. The suits may or may not be symptomatic of the presence of a ticket.
According to Wikipedia, a patent thicket is “a dense web of overlapping intellectual property rights that a company must hack its way through in order to actually commercialize new technology.” (Actually, they are just quoting Carl Shapiro, who first coined the term to describe the problems from Intel’s perspective.)
Is a thicket what we see in the picture above? Maybe. All those suits could arise from a patent thicket. But also maybe not. All those suits also could arise from legitimate overlap in technical innovation, or merely from the accumulation of (mostly minor) legal maneuvering. It is hard to tell without a lot of detail.
However, the article about the smart phone industry has plenty to say about divided technical leadership. If you read between the lines, the article also has a bit to say about the relationship between divided technical leadership and lawsuits.
What is divided technical leadership? This is a phrase coined by Tim Bresnahan and myself back in 1999 in an article about the role of platforms in the computer industry. For a definition, let me quote my review of the literature about innovative conduct in the computing industry, which was recently published in the Handbook of the Economics of Innovation. There I paraphrased our prior work, calling an increase in divided technical leadership “…an increase in the number of firms that possess the necessary technical knowledge and commercial capabilities to bring to market some component or service of value to computer users. ”
The division of ownership is a structural feature of the setting — that is, it changes very slowly, over many decades (but not much one year to the next). This structural feature contrasts with with another kind of structure, where one firm owns all or most of the intellectual property, or one firm employs most or all of the technically skilled engineers in an industry. In such a setting the dominant firm has considerable say over the rate and direction of innovation.
Think of IBM in 1969 in computing, or AT&T in 1948 in telephony, and you get the picture of an industry with concentrated technical leadership. One firm dominates innovative activity due to the ownership over technical skills and the complementary capabilities to commercialize those technologies.
So here is the interesting open question. The phone system is not the same one used by your parents or grandparents. The division of technical leadership in communication equipment markets today did not arise from one person’s design. It was not easy moving from the world of unified technical leadership to one of divided technical leadership, but it did happen (*and in spite of some spirited attempts to resist it*).
But all that history does not explain the fundamental fact: Why so many lawsuits?
One potential explanation is straightforward. In a world of divided technical leadership many firms innovate and in overlapping directions. Unsurprisingly, any reasonably valuable innovation has several inventors near it or close to it or on top of it.
Another relevant question concerns the propensity to patent. Why would commercial firms patent their innovations instead of keeping their secrets? There is a simple answer: the patent system gives them every incentive to patent instead of keep secrets.
It would be a grave mistake to be left without any patents. Unilaterally NOT PATENTING would be a foolish strategic error, making a company vulnerable to suits from others who easily obtained patents. Most firms recognize the need to possess some patents to use as weapons in the event that others sue them. In a world of divided technical leadership there are multiple opportunities for such suits to arise.
Let me rephrase that. Patents are not expensive in comparison to the rewards. Suits in lucrative markets such as cellphones involve awards in the hundreds of millions of dollars. If the R&D and patent costs a couple hundred thousand dollars it would be worthwhile to expend the money, and often innovations and patents cost a lot less.
That still does not get to the central question. Owning the patent is not the same as suing with it. Even if firms have many patents, they may not sue with them. Why so many lawsuits in smart phones?
First, let me question the premise of the question. I am not sure there are many lawsuits. As a fraction of total patenting, what is the propensity to bring a suit in this setting? Does it differ from most other markets? I am not sure.
Second, many firms might be better off with agreements in advance about who owns what, avoiding the lawsuits. That does happen from time to time when the standards processes sort through patent ownership in advance and design compatibility standards between components.
For example, there have not been a plethora of lawsuits over wi-fi. Even the DVD consortium has managed several upgrades to the technology without falling into disarray.
Why did the smart phone fall into this pattern of lawsuits? Honestly, I do not know. It would be useful to hear from some insiders about it. What do you think?
