Afilias’ European Device Detection Patent Invalid

DeviceAtlas a trivial variation of WURFL

Yesterday the European Patent Office (EPO) opposition division narrowed Afilias Technologies Plc’s device detection patent EP2245836B1 in Europe, as a result of an opposition brought by 51Degrees in 2017 and explained in this blog. The EPO concluded that the patent as initially granted was not valid.

Act now to make the most of 5G

Why the world needs 5G and how it will impact the Programmatic Advertising & Publisher industries

James Rosewell, CEO & Founder of 51Degrees, asks why the world needs 5G and how it will impact the Programmatic Advertising & Publisher industries. 5G isn’t a tactical issue to be addressed in 2018 alongside header bidding, viewability or brand safety. It is, however, something to put on the strategic roadmap and to start preparing for. 5G presents a clear opportunity for Adtech and Publishers to address many systemic problems over a realistic timeframe. Prepare now to embrace the 5G opportunity in the early 2020s.

DeviceAtlas Patent Opposed

51Degrees leads opposition to Afilias European patent

In July 2017, after eight long years of deliberation, the European Patent Office (EPO) finally granted Afilias Technologies Ltd patent EP2245836B1 "Determining a property of a communication device". 51Degrees, the company I founded and still run, opposed this patent not because we think it affects any of our current products but because it attempts to monopolise the earlier WURFL (Wireless Universal Resource FiLe) solution now run by ScientiaMobile along with other well-known computing techniques.

Enhance Conference and the User-Agent

Misconceptions concerning User-Agents are limiting the possibilities

Friday 4th March 2016 saw 180 web professionals all with an interest in progressive enhancement assemble in London for a one day conference organised by Simon McManus.

"The Web is the most hostile software engineering environment imaginable." - Douglas Crockford

I continue to be amazed at how the humble User-Agent is misunderstood. My purpose in writing this blog post is to reset some myths passed down from web professional to web professional over the years concerning User-Agents. This was typified in the debate and conversation I witnessed at Enhance Conference.

API Version 3.2 Update for Developers

Details of features and release schedule for API updates

We’re always working hard to improve the 51Degrees APIs making them easier to use, consume fewer resources and provide new features. Version 3.2 combines many incremental changes. Highlights included in all API variants are:

  • New version 3.2 data file is 25% smaller than version 3.1. Data file size is no longer proportional to supported Device Combinations and Signatures. As a result V3.2 data files will grow at a slower rate than V3.1.
  • C APIs now join PHP, .NET and Java in supporting multiple HTTP headers, not just User-Agent. The developer no longer needs to consider which headers to use.
  • Cache structures are now all memory limited rather than time limited resulting in a more consistent memory profile.
  • Information relating to false positives such as rank information is returned more quickly.
  • Github is the master repository for all API source code. Mirrors will be maintained on Codeplex, Sourceforge and other locations.

Apple Standalone on Device Detection

Exposing the crippling solution used to detect iPhone and iPad models

Device vendors as varied as the mighty Samsung, to brands like Pantech and Micromax all recognise the importance of identifying different device models when accessing web sites. However, Apple do not fully support this approach.

Some device detection solutions have tried to address the problem by artificially stressing the iPhone or iPad to determine how quickly its processor can complete iterative tasks. Understanding how the device performs under stress provides an indication as to the CPU available and therefore the model of the device. The approach can yield more information but ironically at the expense of user experience as the page load time increases and the battery is drained more rapidly.

If every web site were to stress iPhones and iPads to gain model information the web would slow down for Apple users. This isn’t in Apple’s interest. However, if Apple make a simple change the problem can be avoided.
