R&D

Technology cycle time is a measure of the pace of technological turnover by measuring the average age of patent citations. The following table shows the UPC subclasses with the fastest moving TCT for 2010. Only subclasses that have received at least 100 patent grants during 2010 are included. Results show communications IT, big data, vehicles navigation, computer conferencing constitute most of the classes.

Auto Maker Patenting Since 2007

Which of the top automakers is leading the software patenting charge towards autonomous vehicles? This chart shows which automakers have been acquiring patents since 2007. Looks like Honda and GM are really collecting the most patents with Nissan in the number 3 position. Expectedly data processing for vehicle navigation is by far the run-away top software UPC for patenting by most auto makers.

Probability of Litigation for Software Patents vs USPTO Average

The first chart below shows the probability that a patent will become litigated for the whole USPTO (blue), commercial and business software IPC G06Q (red), and the total G06Q patent issued per year from 1990-2011. The chart tells the story pretty clearly. That is, software patents have a much higher possibility of litigation than average for the whole USPTO. Also, commercial software patenting is increasing significantly to over 3000 patents per year. In this data model probability is calculated by the number of litigated patents each year divided by a cumulative total of issued patents in each category starting in 1976. While patenting is increasing, litigation is increasing faster. The actual probabilities may be slightly higher than shown here considering that the cumulative totals are run from 1976 until the calculated year. The second chart showing the average age of litigated patents for the entire USPTO and G06Q show that…

US Dominates Software Patents.. But Do They Have Any Value?

The uncertainty in the dragons den of software patents may be driving many countries away from competing for patents. This is perhaps bad news for the US and further evidence that software patents restrict innovation. Considering that only 12.9% of software patents hold up upon litigation ( The study was carried out by John R. Allison, Mark A. Lemley & Joshua Walker for McCombs Graduate School of Business, University of Texas at Austin). The data are actually quite staggering. The chart above shows that the US holds approximately 55% of all USPTO patents in existence. On the other hand, The US holds almost 70% of all software patents in the US and even more staggeringly 85% of all business and commercial software patents.

TCT of Autonomous Vehicle IPCs

Is using Technological Cycle Time (TCT) an acceptable way to evaluate the vitality of an industry? If a firm was looking into expanding their core R&D competencies would an industry with a faster growth rate attract them? Rapid growth in an industry is like a forrest full of deer. Easy hunting and big rewards. On the other hand, stagnation can occur within a sector when serious technological hurdles start to slow the pace of development. In that situation, technological breakthroughs are needed in order to pave the way for continued growth (Kayal, 1999). According to Kayal’s theories and observations regarding technological progress in the superconductor and semiconductor fields, looking at the TCT for an industrial sector can give you an idea about the pace of technological development taking place. TCT of several IPCs is shown (thin colored lines) below. The overall range is generally between 5-8. All the IPC’s closely…
