Samsung, not IBM, owns the biggest US patent portfolio, the IAM/ktMINE US Patent 100 reveals

London, UK – Asian entities have seven of the 10 biggest active US patent portfolios, according to research exclusively compiled for IAM by IP data and analytics platform ktMINE.

Korean company Samsung sits at the top of the tree, with 75,595 active assets as of January 1 2018 – nearly 30,000 more than IBM, which had 46,443. Rounding off the top five are Canon, Microsoft and Intel. Between them, these five businesses owned over 225,000 active patents on the first day of this year.

The IAM/ktMINE US Patent 100 lists the 100 entities that own the most active US patents. The list features in issue 89 of IAM, which is now available to subscribers.

As well as overall portfolio size, the list details pending applications, ratio of application to grants and the percentage of applications published in 2017. Separate tables provide information on the companies with the highest grant to applications ratios and high application activity.

That Samsung’s active portfolio is so much bigger than IBM’s may come as a surprise to many, given that Big Blue perennially tops the annual tables for most US patent grants received and did so for the 25th consecutive year in 2017. However, IBM’s abandonment rate is particularly high and so many of the patents it receives do not stay in its portfolio for very long. Samsung, on the other hand, is more likely to keep hold of its rights – and is more active in more technology areas.

Overall, there are more US entities than any others in the IAM/ktMINE US Patent 100, although the Asian companies in the list hold more patents in total. Europe has 14 entrants in the 100, the highest being Nokia in 18th position.

The full top 10 of the IAM/ktMINE US Patent 100 is:

  1. Samsung
  2. IBM
  3. Canon
  4. Microsoft
  5. Intel
  6. Panasonic
  7. LG Electronics
  8. Sony Corporation
  9. Hitachi
  10. Toshiba

To create the IAM/ktMINE US Patent 100, ktMINE analysed patent publications to determine granted and pending patent applications in good standing. Granted patents’ data includes utility patents along with design and plant patents.

Patents and applications that had expired, been abandoned or were otherwise unmaintained were excluded from the dataset.

The data is current as of January 1 2018.

To get the results, ktMINE technology aggregated each granted patent and application to its corresponding corporate tree in order to create the most up-to-date and complete portfolio. Each entity was designated by the location of its corporate headquarters for supplementary analysis.
