Zillow is back on our radar after acquiring the latest in a long list of vague, over-reaching patents (that our government continues to grant to them). This time, they’re going after data – specifically regional rates of return on home improvements.
The patent in question describes a “facility” (later described as a “computer-readable hardware device”) that can estimate housing prices in a given geographic area, but the real crux of the patent is the home improvement feature. The aforementioned facility can be used to determine how much of a financial return will be present upon completion or categorization of work done on a specific property within that same geographic framework.
Sales estimates generated by this facility will also take into account “type[s]” of home improvement, thus further streamlining Zillow’s notorious “Zestimate” feature.
The way this process works is also mentioned in the patent. According to the abstract, the facility takes regional data regarding homes’ “attribute values” and then compares that data to any available home improvement information. An analysis involving that information along with the difference between the sale price of a property and Zillow’s automatic valuation generates an estimate of the rate of return on the home improvements in question.
As far as Zillow patent grabs go, it’s worth noting that this one has a high degree of specificity in its description – something that was missing from many of the other patent applications they’ve filed in the last decade or so – though some aspects of the patent lapse into Zillow’s aloof rambling of late.
For example, the background on the patent says that “…the facility may use a wide variety of modeling techniques, house attributes, and/or data sources. The facility may display or otherwise present its home improvement rates of return in a variety of ways.” That isn’t particularly specific to a style of data representation, freeing up the real estate giant to enforce this patent on a more general level.
And the problem with the remaining specificity is that it details everything from the natural flow of data and the process of comparison to the physical configuration of the hardware used to process that data – which may make it difficult for many technologists in the space to generate similar data without falling into the dangerous zone of violating the patent simply by using common sense.
This is the M.O. over at Zillow Group. Unfortunately, the patent was just granted, which means smaller real estate ventures will need to keep an eye on the way they process regional data pertaining to home improvement values.
